If your site takes too long to load, visitors leave, and search engines notice. One of the most effective ways to improve performance without upgrading your entire infrastructure is by using web caching.<\/p>\n\n\n\n<p>Web cache allows your website to load faster by storing copies of your content and serving them instantly to visitors. When implemented correctly, caching can significantly reduce server load, improve SEO rankings, and enhance overall user satisfaction.

This data is usually a copy of files already existing in a larger and slower storage unit. In web hosting terms, cache is a copy of your website collected and stored on various servers and browsers. The aim is to display your website faster in the visitor&#8217;s web browser.<\/p>\n\n\n\n<p>For example, imagine you are cooking. Naturally, you are following a recipe. This recipe is, of course, situated in a book, placed on your bookshelf in your living room. Going there to check each step will be highly time-consuming and frustrating. You will spend more time walking between the kitchen and the living room, finding the book, and then finding the correct page where the recipe is situated.<\/p>\n\n\n\n<p>Instead, you can rewrite the recipe on a smaller piece of disposable paper and take it to your kitchen with you. Now cooking will be a lot quicker, and you won&#8217;t need to take the same prolonged action to see each following step. Moreover, you can discard the copy at some point but still have the original.<\/p>\n\n\n\n<p>The cache works the same way. Whenever you visit a website for the first time, your web browser stores the content and the design of the pages you open in its internal memory. This way, the next time you open the same website, it will take just a fraction of the time to open, as your browser already has a copy of it in its cache. Of course, there is way more complexity and of course different type of caches but more on that later in this post.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1110\" height=\"600\" src=\"https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2-1110x600.png\" alt=\"Why is Cache so important\" class=\"wp-image-3311\" srcset=\"https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2-1110x600.png 1110w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2-300x162.png 300w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2-768x415.png 768w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2-24x13.png 24w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2-36x19.png 36w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2-48x26.png 48w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/loading-speed-2.png 1200w\" sizes=\"(max-width: 1110px) 100vw, 1110px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-is-web-cache-so-important\"><span class=\"ez-toc-section\" id=\"Why_Is_Web_Cache_So_Important\"><\/span>Why Is Web Cache So Important?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The benefits that caching brings are immense. Here&#8217;s why it&#8217;s important:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-improved-web-experience\">Improved Web Experience<\/h3>\n\n\n\n<p>Websites can be delivered to visitors more quickly and efficiently using cache. Server and browser cache allow users to get to the content more easily and in a fraction of the time. This eliminates entirely the need to generate the page from scratch on the server for subsequent use. Naturally, this leads to a far better user experience and SEO.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-reduces-server-load\">Reduces Server Load<\/h3>\n\n\n\n<p>Moreover, caching can help immensely in relieving some of the server load. When a page is cached, returning users&#8217; browsers don&#8217;t need to request any data from the server. This can significantly improve the server&#8217;s processing and response time. Ultimately, this will lead to more traffic without the need for additional server resources.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-reduces-infrastructure-costs\">Reduces Infrastructure Costs<\/h3>\n\n\n\n<p>Along with better traffic, cache allows you to grow without significant additional expenditure. Ultimately, you will need to reinvest and implement additional capital, but still, it&#8217;s far better to do so once your business has already developed and the revenues are already flowing in.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-reduces-bandwidth\">Reduces Bandwidth<\/h3>\n\n\n\n<p>Among other things, caching will reduce the amount of bandwidth you need. This will allow you to use a more affordable plan while still enjoying constantly increasing traffic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-improves-seo\">Improves SEO<\/h3>\n\n\n\n<p>Furthermore, caching your website will benefit your SEO efforts significantly. Though Search engines don&#8217;t list page speed as necessarily a requirement to be positioned on their first page, they opt for the most user-friendly website with a low bounce rate and high traffic. Therefore, as users prefer faster websites, search engines will consider faster websites to be more user-friendly, thus pushing them forward in their search results.<\/p>\n\n\n\n<p>As you can see, caching is not only a recommendation but a necessity.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1110\" height=\"600\" src=\"https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1-1110x600.png\" alt=\"Website Cache\" class=\"wp-image-3312\" srcset=\"https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1-1110x600.png 1110w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1-300x162.png 300w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1-768x415.png 768w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1-24x13.png 24w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1-36x19.png 36w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1-48x26.png 48w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/web-cache-1.png 1200w\" sizes=\"(max-width: 1110px) 100vw, 1110px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-does-the-browser-cache-work\"><span class=\"ez-toc-section\" id=\"How_Does_the_Browser_Cache_Work\"><\/span>How Does the Browser Cache Work<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Browser cache is one of the two instrumental components of storing your website off-server. The browser cache usually stores static resources such as HTML files, CSS stylesheets, JavaScript files, and media on the visitor&#8217;s local device.<\/p>\n\n\n\n<p>This means that if you use your PC to access our website, <a href=\"https:\/\/hostarmada.com\/\">hostarmada.com<\/a>&#8216;s static data will be copied to your local browser. This way, if you revisit us, your browser won&#8217;t have to request the cached static data from our servers a second time. On the other hand, if you open it a second time from another device (Laptop, Tablet, Phone), as the cache is only stored locally on your PC, it won&#8217;t help you open the website faster, despite being in the same network. Of course, our website is well-optimized, and the difference will be barely noticeable, but still, it is there, and it helps a lot.<\/p>\n\n\n\n<p>Browser caching is a highly complex process that&#8217;s hard to explain in simple terms. In a nutshell, however, here is how it works:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-initial-visit\">1. Initial Visit<\/h3>\n\n\n\n<p>When you enter a domain name for the first time, the browser goes through the <a href=\"https:\/\/www.hostarmada.com\/blog\/what-is-dns-and-how-does-it-work\/#The_8_steps_of_opening_a_website\">8-step process<\/a> to acquire the website&#8217;s data from the server. During the process, the browser retrieves all HTML, CSS, JavaScript, and media resources to load the website on your screen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-caching-of-resources\">2. Caching of Resources<\/h3>\n\n\n\n<p>While displaying the website on your screen, the browser makes a copy and stores it as a hidden file on your device in a cache folder or another storage area. The stored cache is strictly related to the URL. This means that if you have <a href=\"https:\/\/www.hostarmada.com\/blog\/\">hostarmada.com\/blog<\/a> cached, your browser will still have to go through all eight steps to retrieve <a href=\"https:\/\/hostarmada.com\/pricing\/\">hostarmada.com\/pricing<\/a>, for example.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-subsequent-visit\">3. Subsequent Visit<\/h3>\n\n\n\n<p>When a domain name is entered in the browser&#8217;s search bar, the first job of the browser is to check all cached files. Then, it will compare the requested URL with the cached URL resources on your device before sending any requests online. That reduces the number of requests your browser will make to the accessed website, thus reducing the overall loading time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-4-cache-hit\">4. Cache Hit<\/h3>\n\n\n\n<p>If the cache is found in your browser&#8217;s internal storage, the cached resources will be loaded from there. Then it ends the process without ever sending a new request online. That&#8217;s why you can visit some websites even when you are offline. It&#8217;s simply a locally stored copy of the website.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-5-cache-miss\">5. Cache Miss<\/h3>\n\n\n\n<p>If, for some reason, the cache record is missing, invalidated, or expired, the browser will send a new request for the same record to the server. When the server delivers the data, the browser will create a new cache for future use.<\/p>\n\n\n\n<p>Along with the browser cache, there is also a server cache.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-does-the-server-cache-work\"><span class=\"ez-toc-section\" id=\"How_Does_the_Server_Cache_Work\"><\/span>How Does the Server Cache Work<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>As we established, when you enter a domain in your web browser&#8217;s address bar, it searches within its internal (browser) caches for data associated with the entered domain. But what happens if there is no data cached, or the cached data is invalid\/expired?<\/p>\n\n\n\n<p>The web browser will request the same data from the server where the website for the entered domain is being hosted. How fast that data will be returned by the server depends on the Server cache. Here is how it works in a simplified manner:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-request-handling\">1. Request Handling<\/h3>\n\n\n\n<p>When there is an incoming request, the server checks for a cached version of the requested data within its cache storage (typically RAM). Just like with browser caching, if there is a server-cached version of the requested data, it will be sent back to your web browser, finishing the process. However, if the cached data is corrupted, missing, or invalid, the server will compile all the website&#8217;s code logic once again.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-storing-new-cache\">2. Storing New Cache<\/h3>\n\n\n\n<p>When the website&#8217;s code logic is compiled, and the data it produces is generated, the server stores it in its internal cache storage and sets a unique identifier. Thanks to that identifier, the server knows where the data is stored, so it can be retrieved immediately when requested again (without compilation).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-web-cache-expiration-and-validation\"><span class=\"ez-toc-section\" id=\"Web_Cache_Expiration_and_Validation\"><\/span>Web Cache Expiration and Validation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Cached data has a predetermined expiration date, which is set by the time the cache is generated. So when a website is accessed, both the web browser and the web hosting server check if the cache they have stored is still valid or needs revalidation. The validation of cached data is measured in time units &#8211; one minute, one hour, one day, and so on. To determine if a cached resource has expired, the web browser and the web server check the current time and then compare it to the expiration time of the cached resource.<\/p>\n\n\n\n<p>For example, if the browser sees that cached data has expired, it sends a conditional request to the server to check for any website modifications. If the data is modified, the server will send it to the browser, and the browser will cache it again. On the other hand, if there are no changes, the server will respond accordingly. Thus, the browser will revalidate its cache with the new expiration time.<\/p>\n\n\n\n<p>Server cache revalidation works similarly. Each cached resource has an expiration date. Once reached, the cache can either become stale or be evicted, depending on how the server was programmed. The former requires the server to revalidate the cache when a subsequent request arrives. The latter forces the server to fetch new data.<\/p>\n\n\n\n<p>The expiration of the cached data (both browser and server cache) is often managed by the settings of your website. In other words, you have direct control over what will be cached and for how long.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1110\" height=\"599\" src=\"https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration-1110x599.png\" alt=\"Browser cache configuration\" class=\"wp-image-3313\" srcset=\"https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration-1110x599.png 1110w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration-300x162.png 300w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration-768x415.png 768w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration-24x13.png 24w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration-36x19.png 36w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration-48x26.png 48w, https:\/\/www.hostarmada.com\/blog\/wp-content\/uploads\/2023\/05\/cache-configuration.png 1200w\" sizes=\"(max-width: 1110px) 100vw, 1110px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-configure-web-cache\"><span class=\"ez-toc-section\" id=\"How_To_Configure_Web_Cache\"><\/span>How To Configure Web Cache<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If you have a custom-built website, configuring the caching might be a bit overwhelming in the beginning.\u00a0 That is why we strongly recommend acquiring the help of a professional web developer for this part, especially if you are operating highly dynamic websites, like e-commerce or a website that gathers sensitive information. If you are a customer of our services, we will be more than happy to help you with the optimization of such a website. Simply <a href=\"https:\/\/hostarmada.com\/contact-us\/\">contact us<\/a>!<\/p>\n\n\n\n<p>On the other hand, if you are using a CMS like WordPress, configuring caches is a matter of installing the correct plugins. But more on that later in this post.<\/p>\n\n\n\n<p>There are, of course, some general recommendations you can consider for caching the static resources of your website in your visitors&#8217; web browsers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-browser-caching-of-static-data\">Browser Caching of Static Data<\/h3>\n\n\n\n<p>To configure browser caching of static resources for an extended period, you will need to modify the content of a file called <a href=\"https:\/\/hostarmada.com\/kb\/websites\/what-is-a-htaccess-file-and-where-can-i-find-it\/\">&#8220;.htaccess,&#8221; which you can find in the root folder of your website<\/a>. Open that file for editing, and at the top of it, add the following lines:<\/p>\n\n\n\n<div class=\"line number1 index0 alt2\"><code class=\"plain plain\">## Mod Expires Headers ##<\/code><\/div>\n\n\n\n<div class=\"line number2 index1 alt1\"><code class=\"plain plain\">&lt;IfModule mod_expires.c&gt;<\/code><\/div>\n\n\n\n<div class=\"line number3 index2 alt2\"><code class=\"plain plain\">ExpiresActive On<\/code><\/div>\n\n\n\n<div class=\"line number4 index3 alt1\"><code class=\"plain plain\">ExpiresByType image\/jpg \"access 1 year\"<\/code><\/div>\n\n\n\n<div class=\"line number5 index4 alt2\"><code class=\"plain plain\">ExpiresByType image\/jpeg \"access 1 year\"<\/code><\/div>\n\n\n\n<div class=\"line number6 index5 alt1\"><code class=\"plain plain\">ExpiresByType image\/gif \"access 1 year\"<\/code><\/div>\n\n\n\n<div class=\"line number7 index6 alt2\"><code class=\"plain plain\">ExpiresByType image\/png \"access 1 year\"<\/code><\/div>\n\n\n\n<div class=\"line number8 index7 alt1\"><code class=\"plain plain\">ExpiresByType image\/svg \"access 1 year\"<\/code><\/div>\n\n\n\n<div class=\"line number9 index8 alt2\"><code class=\"plain plain\">ExpiresByType text\/css \"access 1 month\"<\/code><\/div>\n\n\n\n<div class=\"line number10 index9 alt1\"><code class=\"plain plain\">ExpiresByType application\/pdf \"access 1 month\"<\/code><\/div>\n\n\n\n<div class=\"line number11 index10 alt2\"><code class=\"plain plain\">ExpiresByType application\/javascript \"access 1 month\"<\/code><\/div>\n\n\n\n<div class=\"line number12 index11 alt1\"><code class=\"plain plain\">ExpiresByType application\/x-javascript \"access 1 month\"<\/code><\/div>\n\n\n\n<div class=\"line number14 index13 alt1\"><code class=\"plain plain\">ExpiresByType image\/x-icon \"access 1 year\"<\/code><\/div>\n\n\n\n<div class=\"line number15 index14 alt2\"><code class=\"plain plain\">ExpiresDefault \"access 3 days\"<\/code><\/div>\n\n\n\n<div class=\"line number16 index15 alt1\"><code class=\"plain plain\">&lt;\/IfModule&gt;<\/code><\/div>\n\n\n\n<div class=\"line number17 index16 alt2\"><code class=\"plain plain\">## Mod Expires Headers ##<\/code><\/div>\n\n\n\n<div>&nbsp;<\/div>\n\n\n\n<div>These rules will instruct your visitors&#8217; web browsers to cache:<\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Image files from your website for 1 year &#8211; Since images are rarely updated and often the largest bits of data on your website, caching these for a longer period is a good choice.<\/li>\n\n\n\n<li>CSS and JavaScript files for one month &#8211; CSS design files and JavaScript files also rarely change. Just in case, the cache of these files will be refreshed every month.<\/li>\n\n\n\n<li>Your website&#8217;s favicon for 1 year &#8211; your website&#8217;s favicon is something that changes quite rarely. So instructing browsers to cache it for one year is also a good choice.<\/li>\n<\/ul>\n\n\n\n<div>Please bear in mind that these rules will work only if you are a customer of our services or if your web hosting provider uses Apache (regardless if standalone or with NGINX as an open proxy) web server with ModExpires module.<\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-object-caching\">Object Caching<\/h3>\n\n\n\n<div>The other type of caching is object caching. Object caching is a technique used to cache the results of resource-intensive operations triggered by the code logic of your website. Such are database queries, API calls, and complex calculations.<\/div>\n\n\n\n<p>To make this abstract definition more obvious, consider websites like TripAdvisor or Amazon. These websites often change their content based on user ratings and filters. The ratings are stored in a database, and the website retrieves and calculates the average rating for each product on every page load. The calculation involves querying the database, aggregating ratings, and performing calculations.<\/p>\n\n\n\n<p>So if there is no object caching, if User A searches for a bike with some implemented filters, the server will execute the database query and retrieve each product&#8217;s ratings that fall under the filtered categories. Then it will calculate the average rating and arrange the products in a certain way. If User B makes the same request without object caching, the entire process will start anew, taking the same portion of server resources. If there is object caching, the list will appear in a fraction of the time.<\/p>\n\n\n\n<p>To configure Object Caching for your website, you need to know how it was developed &#8211; is it based on an open-source platform like WordPress, or is it based on custom code done by a development team? If your website is based on WordPress, you can easily find a plugin that can help you out in the configuration of Object Caching. Such are, for example, W3 Total Cache, WP Rocket, and many more. If your website is custom-developed, then your best choice would be to contact the developers or hire a new dev team.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-wordpress-plugins\">WordPress Plugins<\/h3>\n\n\n\n<p>WordPress plugins are hands down the easiest solution to your caching needs no matter the type of caching you need. Whichever one you choose, they all have an easily navigable interface and make your cache configuration extremely easy and fast. You only need to look out for whether the chosen plugin is compatible with your WP version, theme, and other plugins. Also, note that using multiple caching plugins will certainly break down your website. <a href=\"https:\/\/www.hostarmada.com\/blog\/hostarmada-top-choice-wordpress-caching-plugins-for-2020\/\">Here is a review<\/a> of the most used ones by our clients.<\/p>\n\n\n\n<p>Most importantly, before implementing any caching plugin, it&#8217;s essential to <a href=\"https:\/\/hostarmada.com\/kb\/websites\/backup-or-restore-your-website\/how-can-i-create-a-backup-of-my-website\/\">backup your website<\/a>, so you can revert any potential mishaps in the process.<\/p>\n\n\n\n<p>For more information or a free consultation with our experts, our clients can open a chat or submit a support ticket.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-cache-pitfalls-you-need-to-know\"><span class=\"ez-toc-section\" id=\"Cache_Pitfalls_You_Need_To_Know\"><\/span>Cache Pitfalls You Need To Know<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Caching your website will undoubtedly improve your website&#8217;s performance. Still, that doesn&#8217;t mean there are no downsides or challenges along the way. Here are a few pitfalls you need to consider when implementing caching.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-incorrect-expiration-time\">Incorrect Expiration Time<\/h3>\n\n\n\n<p>Implementing the correct expiration time for cache can be a bit tricky. If you set the expiration time for too long, users will see outdated content. On the other hand, if it&#8217;s set too short, it will defeat the purpose of having a cache in the first place. Setting the right expiration time will maximize the benefits while ensuring all users receive your latest updates.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-messed-up-cache-invalidation\">Messed up Cache Invalidation<\/h3>\n\n\n\n<p>This is another major challenge with caching. Just like with expiration times, if you set the invalidation process improperly, people will see outdated or wrong information. Therefore, a solid invalidation strategy is crucial for fresh content flow.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-inconsistent-cache\">Inconsistent Cache<\/h3>\n\n\n\n<p>There is rarely a bigger disaster for a website than having an inconsistent cache across multiple servers. If this happens, different users will receive different information, which will hinder your credibility and authority.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-cache-stampede\">Cache Stampede<\/h3>\n\n\n\n<p>This occurrence happens when a lot of cached items expire simultaneously, and all request revalidations from the server at the same time. This will overload the server and cause performance issues. This is why cache expiration is an art form that you shouldn&#8217;t take lightly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-overall\"><span class=\"ez-toc-section\" id=\"Overall\"><\/span>Overall<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Despite the minor drawbacks, one can not argue that cache is one of the most essential optimizations for your website, which will help you increase your website speed immensely. For your users to always enjoy your website on demand, you need fast, reliable, and secure web hosting. Luckily, <a href=\"https:\/\/hostarmada.com\/\">HostArmada<\/a> is here to help.
