Summary: If-Modified-Since support
Initial Comment:
WebKit makes no use of the If-Modified-Since HTTP header,
which makes static content service inefficient.
Of course, you can move your static content to a separate
HTTP server, but adding support for If-Modified-Since
buys most of the benefits and costs little.
The attached patch modifies mod_webkit to pass
the If-Modified-Since header via the request environment
dictionary. While arguably less than elegant,
this does the trick.
The patch to UnknownFileTypeServlet checks the
IMS value against the file's mtime. If it matches,
it sets "Status 304" and sends no content.
(It also corrects some unlikely but possible bugs.)

Ken,
Have you any test scripts to verify that the IMS is working
as expected?
Also, is there more to the isAuthenticated() method? It
does not appear to be related to IMS.
There are some other issues addressed in the
UnknownFileTypeServlet apparently. Can you provide a
description of changes in functionality here? It's not
clear how much of that is needed.
-- Thanks --

Here is a third version of the patch, against today's CVS.
The PSP caching is now off by default, to avoid breaking
existing code.
I've added a patch to mod_webkit2.
The patch to UnknownFileTypeServlet includes changes made in the
meantime.

Here is an improved version of the above patch.
This version moves the
If-Modified-Since logic up to the HTTPServlet level,
so it may be used by other factories. I've modified PSP
so that "static" PSP pages may be cached at the client.
("Static" pages are those that don't use any dynamic PSP
hooks.)
There's also a fix to a typo in Session.py.
