Configure Page Output Caching in a web configuration file and apply the settings to multiple pages. 
You can set the same caching properties in a Cache Profile as you can set in an individual page's <%@ OutputCache %> directive. 

A Cache Profile named Cache1Hour that caches a page for one hour.

File: Web.Config

<configuration>
  <system.web>
    <caching>
      <outputCacheSettings>
        <outputCacheProfiles>
          <add name="Cache1Hour" duration="3600" varyByParam="none" />
        </outputCacheProfiles>
      </outputCacheSettings>
    </caching>
  </system.web>
</configuration>
