You could use __bobo_traverse__ or __get_item__ for this. It'll enable URLs 
like:

   http://your.zope.server/Session/0x1234/SQLMethod/city/New%20York/

where Session is an instance of a Python class you've written. It's 
__bobo_traverse__ method will be called with the 0x1234 part of the URL and 
the REQUEST object, while __get_item__ will only get the 0x1234 part. See 
lib/python/Shared/DC/ZRDB/DA.py for an example, the second part of my 
example URL is implemented there (ZSQL Methods support direct traversal).
