Clear Output cache..??

[Question123]

Hi
i have added a tag to the asp.net page .aspx
<%@ OutputCache Duration="600" VaryByParam="*" %>

it caches the whole page. But problem is that after logout its not getting cleared and if i tried to loggin with some other user it shows old data cached for previous user.

Please give me solution so that i can clear Output cache on user logout.

If the logout is destroying the session correctly, then you can tell ASP.NET to cache pages for the current session only.

First you need to add VaryByCustom=”SessionID” to the OutputCache directive. Then you simply override (in global.asax) GetVaryByCustomString to return that sessionID.
something like:

 
Public override string GetVaryByCustomString(HttpContext context, string arg) {       
 
   if(arg.ToLower() == “sessionid”) {
       HttpCookie c = context.Request.Cookies[“ASP.NET_SessionID”];
       if(c != null) return c.Value;
   }
   return base.GetVaryByCustomString(context, arg);
}  
 

P.S: I'm not a .NET programmer so you need to verify that my code is syntactically correct
