Configure OutputCache for ASCX from web.config's cache profiles

To configure aspx pages' OutputCache from one place, there is a great tool which is the CacheProfile attribute in <%@ OutputCache %> associated with a custom cache profile defined in the web.config :

<开发者_高级运维;caching>
      <outputCacheSettings>
        <outputCacheProfiles>
          <add name="myProfile" duration="300"  />
        </outputCacheProfiles>
      </outputCacheSettings>
    </caching>

And the line :

<%@ OutputCache CacheProfile="myProfile" VaryByParam="None" %>

does the job. But how to do the same thing for ascx user controls ? CacheProfile isn't in <%@ OutputCache %> :S Is there a workaround ? Thanks.

From http://msdn.microsoft.com/en-us/library/hdxfb6cy.aspx :

"Either this attribute (VaryByParam) or the VaryByControl attribute is required when you use the @ OutputCache directive on ASP.NET pages and user controls. A parser error occurs if you fail to include it."
