Hello,

I am trying to dump the cache on my home page.  that when I pass a value w=1

but it's not working any ideas? 

<%@ Page Language="VB"  Debug="true"  ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ OutputCache Duration="3600" Location="Server"  VaryByParam="none" %>

<%

if request.QueryString("w")="1" then

    Dim path As String
    path="/default.aspx"
    HttpResponse.RemoveOutputCacheItem(path)
 
end if

%>
 

Hi,

you can use Response.Cache.AddValidationCallBack See: http://www.hanselman.com/blog/AdvancedASPNETCachingAndAddValidationCallBack.aspx

You can also use RemoveOutputCacheItem but it must get absolute virtual path, plus you must ensure that the code runs (it won't run on the same page when page is in output cache) e.g run on different place (say in global.asax's events or this Validation callback). More information about remove techniques: http://aspalliance.com/668

Thanks for the help.

you answered my question.  this was the key hangup.

(plus you must ensure that the code runs (it won't run on the same page when page is in output cache))

 
I was running the code on the page that had the outputcache.

thanks for your help.
