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

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" %>
