Does SetVaryByCustom work in User Controls?
<p>It seems to me that </p>

<pre><code>Response.Cache.SetVaryByCustom("mykey");
</code></pre>

<p>is not working from within ASCX User Controls. It works from the Page. The ASCX works only when VaryByCustom is specified in the outputcache directive. </p>

<p>I'm using ASP.NET 3.5. </p>

<p>Any help?</p>
