I'm not sure that we should be arguing to include something that depends
on a specific environment like Apache in the standard library. We should
certainly be trying to promote a standard of some sort, however, which
seems to conflict.
I see the parallel more as being with the DB API - there are Oracle
modules and ODBC modules (which are cross-engine) and SQL Server modules
and so on. What we need is something to provide closely similar
interfaces to different web server engines - whether those engines are
in pure Python or external components.
The one problem I see with mod_python is its defaulting behavior - you
can get the same content several different ways. Specifically, the
all refer to the same content, and this makes it rather difficult to
come up with a scheme for producing sensible relative URLs -- the
browsers don't always interpret the path the same way the server does --
which in turn can make it difficult to produce easily portable web
While this is probably not an issue for the standard library I'd like to
know whether anyone has actually addressed the problem. My own solution
is to canonicalise everything to be explicit, but if there's an easier
way I'd love to hear it.
