[Zope] cookie crumbler - preserving variables in URL

[David Siedband]

I'm using cookie crumbler for authentication

Often, the pages that require authentication have a variables on the 
end of the URL.

http://www.site.org/updateListing_html?pid=22

After authentication, these variables get dropped generating an error 
for the dropped variable

redirects to:

http://www.site.org/updateListing_html

How can I modify the cookie crumbler methods to pass these variables 
and redirect to the proper URL?

thanks
