    @iamkingsleyf, you can enable mod_deflate module from Plesk > Tools & Settings > Apache Web Server

    > also this tutorial did not work as apache failed to start

    Can you share the error message?

    Alexander, I'm running Plesk Onyx on Centos, and I followed your instructions and it works fine, thank you. However, I am wondering about "ETag none"  as I'm trying to find best way to always serve image files that have been modified yet cache may still be holding unmodified version.  I just was reading about using ETag and I remembered that I turned it off by following this instruction.   So, will these instructions still work if I remove "ETag none" ?  or do you have suggestion using Apache to always serve modified content?

    @Stuart de Usoz,

    Hello! You may remove "FileETag None" from Apache config file. As far as I know, 'mod_expires' should not conflict with 'ETag'

    @1and1 Internet,

    Hello! You should use only the command from step #1:

    # find / -name mod_expires.so

    And `/usr/lib64/httpd/modules/mod_expires.so` is it's output.

    Hi I have a Ubuntu enviroment and it does not work. 

    If I try the second thing I get already a error: # find / -name mod_expires.so
    find: '/sys/kernel/security/ima': Permission denied
    find: '/sys/kernel/security/apparmor': Permission denied
    find: '/sys/kernel/debug': Permission denied

    nevermind it is in /usr/lib/apache2/modules/mod_expires.so

    #3 would be # vi /etc/apache2/plesk.conf.d/expires.conf

    #4 interestingly there you have the right path

    #5 tried with that string and without

    #6 and #7 no error works fine

    #8 mod_expires does not apear in the list of loaded Apache modules

     

    any idea what I can do next? 

     

    cheers,  Armin

    just found the solution: move /etc/apache2/plesk.conf.d/expires.conf to /etc/apache2/conf-available/expires.conf and than link it in /etc/apache2/conf-enabled/expires.conf to the available conf file restart apache2 and it works fine

    Where is the guide "For particular subscription" ??? Because I don't think this is correct :

    For RHEL-based operating systems (CentOS, RHEL, CloudLinux, Virtuozzo Linux 7)

    1. Comment the line LoadModule expires_module modules/mod_expires.so in the file /etc/httpd/conf.modules.d/00-base.conf.

    2. Create the configuration file /etc/httpd/conf.d/expires.conf:

    To enable leverage browser caching on Apache, please follow these simple steps:

    1. Login into your Cpanel.
    2. Locate the .htaccess file in the root directory.
    3. Open the .htaccess file in your web browser.
    4. Append IfModule code in your .htaccess file provided below.
    5. Finally, save the .htaccess file and test results.

    <IfModule mod_expires.c>
    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"
