[pyOpenSSL] pyOpenSSL and select compatibility under Windows

[Hugh Gibson]

Hi,

We have a server written in Python using a select() loop on the main 
thread to drive socket IO, with our own HTTP 1.1 implementation. It uses 
worker threads to process requests. At present login to our AJAX 
application is handled by our own challenge/response system but we want 
to move to SSL.

I'm trying to determine if pyOpenSSL sockets are compatible with 
select() under Windows so that we can slot them into place.

It seems from http://docs.python.org/lib/module-select.html that there 
might be problems:
    "On Windows, the underlying select() function is provided by the
     WinSock library, and does not handle file descriptors that don't
     originate from WinSock."

Has anyone used this combination successfully?

I've tried stunnel and that works fine enabling SSL connections to our 
server, but I need a way to determine if a connection came via stunnel 
or directly otherwise a client could connect directly to the server.
