The following default outputCacheProfiles element is not explicitly configured in the machine configuration file or in the root Web.config file, but is the default configuration returned by application in the .NET Framework version 2.0.

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

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.
