Apparently, like AJP/mod_jk, mod_scgi does not pass in sane values for SCRIPT_NAME/PATH_INFO. Accept a scriptName keyword to scgi.WSGIServer and deduce SCRIPT_NAME/PATH_INFO appropriately.

I've tenatively repackaged the WSGI servers, middleware, and publisher into the "flup" package (named after the project that spawned all these modules). For now, you can get it from the SVN repo at <http://svn.saddi.com/flup/trunk>.

Pros: allows me to refactor (especially the servers). There are 3 types of servers (fcgi, ajp, scgi) with 2 flavors of each (threaded, forking). Better organized, easier to maintain.

Cons: No more single-module servers or publisher. No more picking and choosing modules. You have to grab the whole package (because of the refactoring).

Added fcgi_fork.py (also dependent on prefork.py), a forking version of the fcgi module.

Added scgi, a threaded SCGI/WSGI module.

ErrorEmailMiddleware was renamed to ErrorMiddleware. It seemed more appropriate since I added a "debug" flag that allows the middleware component to be used during development. (I end up creating a similar component during development... why continuously re-invent the wheel?) Added support for "internal" redirects in Publisher. The Resolver interface has changed slightly as a result.

The Resolvers in Publisher have been updated to ignore URL path parameters. Added JSessionService, a subclass of session's SessionService class, that supports AJP's sticky-session feature.

The environment variable used to force CGI behavior has been renamed to FCGI_FORCE_CGI (previously MAC_OS_X_FORCE_CGI).

Added ErrorEmailMiddleware, a WSGI middleware component that catches any unhandled exceptions from the application. When an exception is caught, a static error page is displayed to the user and details about the exception are emailed to an administrator.

The fcgi module no longer handles multiple requests per connection by default. This was done to eliminate the need for a thread-per-request and thread locking. The non-multiplexed version runs slightly faster.
