Configuring caching

Libraries, such as image or video libraries, support output (server) and client (browser) caching. Configuring caching increases your performance.

Output and client caching are controlled with cache profiles, which you can configure in the following way:

1. Click Administration » Settings.
   The Basic Settings page appears.
2. Click Advanced link.
   The Settings page appears.
3. In the left pane, click System » Output Cache Settings.
   The following globally available caching profiles appear:

   Type of caching	Available profiles
   Output Cache Profiles	No caching The output caching is disabled for this profile. Output will not be cached. Standard caching This is the default profile for all content. It is set to expire in 120 seconds and SlidingExpiration is enabled. Long caching It is set to expire in 1 200 seconds, absolute time.
   Client Cache Profiles	No caching The client caching is disabled. No expiration of the content will be set and the actuality will be verified for every page request. Standard caching This is the default profile for all content. It is set to expire in 90 days from the request. Long caching It is set to expire in 1 year from the request.

   These profiles are applicable to page and content caching.

You can set cache profiles to individual pages or libraries. If no profile is set to a page or library, the default profile is applied. You can change the default profiles and you can globally turn on and off output and client caching, regardless of individual settings made on pages and libraries.
