 How to fix - Image Caching Test

In order to reduce the number of HTTP requests, you can use the HTTP Expires header to set an expiration time for your images or any other content type. You can add the following lines into your .htaccess file:

<IfModule mod_expires.c>

    ExpiresActive on

 

    ExpiresByType image/jpg "access plus 1 month"

    ExpiresByType image/jpeg "access plus 1 month"

    ExpiresByType image/gif "access plus 1 month"

    ExpiresByType image/png "access plus 1 month"

</IfModule>
