redirect before headers are sent

This is related to Bricolage by proximity, because I have to

authenticate on an IIS machine, and redirect to an Apache
server. On the 
  Apache server I have to check for a cookie and either
redirect to the 
IIS server or load a page. The pages are all built by
Bricolage. Mason 
is not available on the Apache server, but Mod Perl is.

The Problem:

I can't find a way to get a cgi script to read a cookie and
redirect by 
using <!--#include virtual or <!--exec cgi, both seem
to be loaded after 
the headers are sent. Does anyone have an idea of how to do
this?

Hmm,... would putting the directive first in the body work?
Or would Javascript be a better way to go? Or is there a
mod_perl module 
that would do it?

TIA

I think you can use mod_rewrite to check for the presence of
specific cookies and that will be your most bullet proof
solution.

This page provides examples:

http://www.askapache.com/htaccess/htaccess-fres
h.html#modrewrite2


I don't believe server side includes will afford you any
opportunity to set HTTP headers since SSIs are inserted into
page content, not responsible for handling / controlling the
request itself.

mod_rewrite would be your most bullet proof solution if you
can get it to work.

Yes, I looked at that and it seemed a bit scary, but I live
for the
thrills anyway.

The trouble with documentation like this is that the people
who write it
long ago forgot how to be confused.

That's what I found.

So off I go to try it.

Thanks for the pointer.
