SCGI-->WSGI application proxy, "SWAP".
(Originally written by Titus Brown.)
This lets an SCGI front-end like mod_scgi be used to execute WSGI
application objects. To use it, subclass the SWAP class like so::
class TestAppHandler(swap.SWAP):
def __init__(self, *args, **kwargs):
self.prefix = '/canal'
self.app_obj = TestAppClass
swap.SWAP.__init__(self, *args, **kwargs)
where 'TestAppClass' is the application object from WSGI and '/canal'
is the prefix for what is served by the SCGI Web-server-side process.
Then execute the SCGI handler "as usual" by doing something like this::
scgi_server.SCGIServer(TestAppHandler, port=4000).serve()
and point mod_scgi (or whatever your SCGI front end is) at port 4000.
Kudos to the WSGI folk for writing a nice PEP & the Quixote folk for
writing a nice extensible SCGI server for Python!

Serve the specified WSGI application via SCGI proxy.
``application``
The WSGI application to serve.
``prefix``
The prefix for what is served by the SCGI Web-server-side process.
``port``
Optional port to bind the SCGI proxy to. Defaults to SCGIServer's
default port value.
``host``

default host value.
``host``
Optional maximum number of child processes the SCGIServer will
spawn. Defaults to SCGIServer's default max_children value.
