[Zope] How to get exact requested URL (was: Current location: is my script reliable?)

[Tonico Strasser]

If you need the exact URL that was requested by the browser including

*) trailing and double slashes and
*) query strings,

then the attached script is for you.

Example usage:

   tal:define="location here/location"
   tal:attributes="href string:$location#documentContent"

I've tested it with several Zope versions and vhost setups.

VIRTUAL_URL

Need "actual URL" method

location = server_url + path_info + query_string

return location
