"the PATHINFO variable" only has meaning in a particular context, here is
the CGI definition:
The PATH_INFO metavariable specifies a path to be interpreted
by the CGI script. It identifies the resource or sub-resource
to be returned by the CGI script, and it is derived from the
portion of the URI path following the script name but
preceding any query data.

Yes, it does:
any extra path information associated with the URL the client sent when
it made this request. The extra path information follows the servlet
path but precedes the query string and will start with a "/" character".
So this definition relies on the notion of a "servlet", which is OK since
this is part of J2EE. Then they go on to say that it is "Same as the value
of the CGI variable PATH_INFO", but it really isn't, "similar" would be a
I think I can live with a pathinfo that is "implementation specific", or
if we were to define a "Python Enterprise Architecture" with our own
definition of a servlet (or whatever), but for the Python standard library
to try to define it *outside of any context* would be a mistake I think.
