Increase page loading speed – Leverage browser caching – .htaccess

How can I enable this via .htaccess file?

Leverage browser caching – It is a simple method to reduce the page loading time of a website for regular visitors.

This technique is useful to speedup pages for websites which has a high re-visit ratio by users. When a web browser loads a web page, it downloads all web file to load the page properly.

It includes HTML, images, CSS, scripts etc. Most of the pages include the same contents repeatedly. In this way we can really reduce the loading speed to a great extent!

Where I can enable this feature?

It’s basically an Apache module and this should be enabled by adding specific code to the Apache configuration file. Most of the users have only user level access to the server.

That’s the important of this post. Here I’m listing a code which can be simply  added to the .htaccess file to enable this feature. The .htaccess is located in the public folder of your website.

Here is the code to add:

ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"

By using the above code, the main static contents such as images, CSS, PDF’s, JS, etc will be cached in web browser in order to produce faster loading time when you visit the site again.

That’s it!
