A redirect is really nothing but an instruction to the browser to change its
address location and request a different page, hence the suggestion to add
something to the URL the client is about to redirect too as a means of
identifying that the redirect occured and re-entered the ISAPI pipeline. So
you could detect it on the way back in and then throw your error.
However, if your working in the ISAPI Pipeline via handlers anyway, you
might want to take a look at the HttpWorkerRequest.EndOfSendNotification
delegate, this occurs when a response is complete - in theory if you issue a
response.redirect and a response.end then this should action as your
response terminates and you may be able to add a means of detecting your
redirection via this.

Hi,
Hmmm.... not a bad thought, however in my app sessions are disabled.
Isn't there some ASP object with some property or something available that
tells you if a redirect is immanent?

news:#C**************@TK2MSFTNGP11.phx.gbl... Hi,
No I can't because the redirect is made and then the code that runs
after the .Redirect line
needs to know if a redirect statement has been made.
Therefore if the actual redirect has not actually taken place yet it's
params won't be available.
Anybody else have any thoughts?

Peter Row
