Session access in MasterPage load event after UrlRewrite

Question

Situation:

• In Web.Config, we included CustomErrors with redirectMode="ResponseRewrite".
• In Page_Loadour MasterPage we get access to the property Session Page.

Problem:

If an error occurs on any page, the user is redirected (via Rewrite) to the Error.aspx page. There, at Page_Load from MasterPage, we access the session and get an HttpException telling us to enable the SessionState. But we have SessionState enabled, definitely.

Question:

How can we access the session after UrlRewrite in the Page_Load event of our MasterPage?

Answer 1

if( HttpContext.Current.Session != null )
{
    //Access Session here...
}

Answer 2

if(Context.IsCustomErrorEnabled)
{
Server.Transfer("~/Error.aspx");
}

Error.aspx Page_Load, .
