fcgi - a FastCGI/WSGI gateway.
For more information about FastCGI, see <http://www.fastcgi.com/>.
For more information about the Web Server Gateway Interface, see
<http://www.python.org/peps/pep-0333.html>.
Example usage:
#!/usr/bin/env python
from myapplication import app # Assume app is your WSGI application object
from fcgi import WSGIServer
WSGIServer(app).run()
See the documentation for WSGIServer/Server for more information.
On most platforms, fcgi will fallback to regular CGI behavior if run in a
non-FastCGI context. If you want to force CGI behavior, set the environment
variable FCGI_FORCE_CGI to "Y" or "y".

Each Connection is associated with a single socket (which is
connected to the web server) and is responsible for handling all

The FastCGI server.
Waits for connections from the web server, processing each
request.
If run in a normal CGI context, it will instead instantiate a
CGIRequest and run the handler through there.

handler, if present, must reference a function or method that
takes one argument: a Request object. If handler is not
specified at creation time, Server *must* be subclassed.
(The handler method below is abstract.)
maxwrite is the maximum number of bytes (per Record) to write
to the server. I've noticed mod_fastcgi has a relatively small
receive buffer (8K or so).
bindAddress, if present, must either be a string or a 2-tuple. If
present, run() will open its own listening socket. You would use
this if you wanted to run your application as an 'external' FastCGI
app. (i.e. the webserver would no longer be responsible for starting
your app) If a string, it will be interpreted as a filename and a UNIX
socket will be opened. If a tuple, the first element, a string,
is the interface name/IP to bind to, and the second element (an int)
is the port number.
Set multiplexed to True if you want to handle multiple requests
per connection. Some FastCGI backends (namely mod_fastcgi) don't
multiplex requests at all, so by default this is off (which saves
on thread creation/locking overhead). If threads aren't available,
this keyword is ignored; it's not possible to multiplex requests
at all.
