Sorry for the non-sequitur.. I do not really know if Zope uses the urllib2
machinery or not. Somewhere, however, there must be some code that catches
raise 'Redirect', myurl
and does the appropriate thing (creates a new request, etc.).
My "find-grep" caught class HTTPRedirectHandler(BaseHandler): (line 427 of
But I have not looked into it enough to understand whether it is what
I am guessing it is, and-- even if so-- whether Zope uses it or not.
in any event, there are other, better solutions on the table, so at this point
it is no longer important...

You're probably right. The browser is getting back a status code in the HTTP
header that makes it generate a new request. The question I had was: would
there be a way to stuff something in the HTTP header that the browser would
somehow copy over to the new HTTP header it sends back in response to the
redirect status code...?
After all, it *does* copy the URL to which it is being redirected, along with
all of its query parameters, etc....
A thorough re-reading of the HTTP spec would probably give me an answer...
