Answer 2

Leverage Browser Caching

Reduce the load times of pages by storing commonly used files from your website on your visitors browser.

To enable browser caching you need to edit your HTTP headers to set expiry dates on certain types of files.

Find your .htaccess file in the root of your domain, this file is a hidden file but should show up in FTP clients like FileZilla or CORE. You can edit the htaccess file with notepad or any form of basic text editor.

In this file we will set our caching parameters to tell the browser what types of files to cache.

The code below tells browsers what to cache and how long to "remember" it. It should be added to the top of your .htaccess file.

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
<IfModule>
## EXPIRES CACHING ##

Recommendations:

• Be aggressive with your caching for all static resources
• Expiry at a minimum of one month
• Don't set your caching more than a year in advance!
