Can't customErrors do in Global.asax

[ad]

I have set customErrors to On and set a defaultRedirect in Web.config like:

<customErrors mode="On"
defaultRedirect="~/ErrorPage/GenericErrorPage.aspx">

When I throw a exception in Global.asax like:
throw new Exception("This a Error Test !!");

It will not redirect to GenericErrorPage.aspx, but if I throw the same
Exception in other web pages, it do.

What is problem? Can't customErrors do in Global.asax?

Ad,
Global.asax isn't a "web page", and it doesn't normally have access to the
Request context process under which normal ASP.NET exception handling occurs.
What exactly is it that you want to do?

Hello ad,

Hmm. strange. Could you show your code? Because <customErrors mode="On" defaultRedirect="Examples.aspx"/>
in Web.config and

protected void Application_Start(Object sender, EventArgs e)
{
throw new Exception("my excep");
}

redirect me to the Examples.aspx page

Peters,
Thanks again.
Maybe there are some condition in my program which affect the redirection
action.
I will check again.
