If you want to reduce the consumption of your server&#8217;s resources, improved responsiveness, bandwidth utilization, availability of content during network interruptions, and give your end users a faster experience, then you need to use the caching that will allow all of this.<\/p>\n<p>A cache is a method for temporarily storing the most requested content so that future requests for that content will be more quickly served by temporary storage (cache) than from the primary location. By using caching, you are efficiently reusing the previously retrieved data.\u00a0Today we are <strong>configuring browser caching control on Apache 2<\/strong>.

However, we need to make sure that our Apache2 together with our module are installed and ready to accept the directives. There is a simple way to verify our module. To list the Apache modules, we will use the apachectl command to list the modules and pipe with the grep command to filter out our results and show only the modules we need.<\/p>\n<p>We can verify the file_cache module with the following command:<\/p>\n<pre>apachectl -M | grep file_cache<\/pre>\n<p>the output should be:<\/p>\n<pre>file_cache_module (shared)<\/pre>\n<p>If you do not have anything in the output after running these commands or it&#8217;s simply blank then the module is not installed. You need to have it installed in order to continue with this tutorial.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3-Enable-File-Caching\"><\/span>3.\u00a0 Enable File Caching<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img decoding=\"async\" class=\"alignleft size-full wp-image-28770\" src=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/10\/How-To-Control-Browser-Caching-with-Apache-2.jpg\" alt=\"How To Control Browser Caching with Apache 2\" width=\"120\" height=\"87\" \/>To use the functionality of the file_cache module you need to enable it first. If you are running CentOS 7 or Ubuntu 16.04, this module by default it is not configured in the Apache so this module will not load. We will show you how to configure and enable the file_cache module in CentOS 7 and Ubuntu 16.04.<\/p>\n<h2><\/h2>\n<h2><span class=\"ez-toc-section\" id=\"4-Enable-File-Caching-on-Ubuntu\"><\/span>4. Enable File Caching on Ubuntu<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you are using Ubuntu 16.04. you can enable the file_cache module with the following command:<\/p>\n<pre>a2enmod file_cache<\/pre>\n<p>Next step is to edit the Apache main configuration file. Open the Apache main configuration file by typing:<\/p>\n<pre>nano \/etc\/apache2\/apache2.conf<\/pre>\n<p>To use CacheFile add this line in the configuration file:<\/p>\n<pre>CacheFile \/var\/www\/html\/index.html \/var\/www\/html\/somefile.index<\/pre>\n<p>If you want to use MMapFile directive instead you should add this line in the configuration file:<\/p>\n<pre>MMapFile \/var\/www\/html\/index.html \/var\/www\/html\/somefile.index<\/pre>\n<p>There should be no reason to configure both CacheFile and MMapFile for the same files, but you can also use them on different files instead. When you finish with configuring the file save and close it.<\/p>\n<p>You can check the Apache configuration file for syntax error with the following command:<\/p>\n<pre>apachectl configtest<\/pre>\n<p>In the end when you receive <strong>Syntax OK<\/strong> you can restart the Apache by typing the command:<\/p>\n<pre>service apache2 restart<\/pre>\n<p>After the Apache will restart, you will start to use the file_cache module on the files you configured.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5-Enable-File-Caching-on-CentOS\"><\/span>5.

Open the Apache main configuration file with nano editor with this command:<\/p>\n<pre>nano \/etc\/httpd\/conf\/httpd.conf<\/pre>\n<p>If you want to use the CacheFile directive to handle caching, you should insert the following line in the Apache configuration file.<\/p>\n<pre>CacheFile \/var\/www\/html\/index.html \/var\/www\/html\/somefile.index<\/pre>\n<p>If you want to use MMapFile directive instead you should add this line in the configuration file:<\/p>\n<pre>MMapFile \/var\/www\/html\/index.html \/var\/www\/html\/somefile.index<\/pre>\n<p>In practice, there is no need both CacheFile and MMapFile directives to be configured for the same files, but you can use them both in the configuration file for a deferent set of files.<\/p>\n<p>When you finish with configuring the file save and close it. You can check the Apache configuration file for syntax error with the following command:<\/p>\n<pre>apachectl configtest<\/pre>\n<p>You should receive <strong>a Syntax OK<\/strong> message, which means that your configuration is correct and you can restart the Apache by executing the command:<\/p>\n<pre>systemctl restart httpd<\/pre>\n<p>In this tutorial, in the first part, we showed you how to check if your file_cache module is enabled on your server.
