<outputCacheSettings>
  <outputCacheProfiles>
    <add name = ""
      enabled = "true"
      duration = "-1"
      location = ""
      sqlDependency = ""
      varyByCustom = ""
      varyByControl = ""
      varyByHeader = ""
      varyByParam = ""
      noStore = "false"/>

Example

The following example caches a page on the server for only one minute and stores different versions of the page based on browser type and major version.

<outputCacheSettings>
  <outputCacheProfiles>
    <add name="ServerOnly" 
      duration="60" 
      varyByCustom="browser" 
      location="Server" />
  </outputCacheProfiles>
</outputCacheSettings>

When designing a page that needs to be cached in this way, you will need to add the following directive to the page:

<%@ OutputCache CacheProfile="ServerOnly" %>

For more information see @ OutputCache.
