I've seen lots of web sites explaining everything, but for whatever reason I seem to not be picking something up. I am a graphical person, which is probably the reason I haven't found my answer. May somebody please confirm if my diagram accurately represents the stack, generally speaking.
http://i26.tinypic.com/1fe82x.png Even if that is the case, I'm having a hard time understanding the differences. I guess wsgiref has absolutely nothing to do with FCGI/ SCGI/CGI and simply receives and responds to HTTP requests following the WSGI specification? Does it just spawn a new thread for each request? If so, then how is this any different than a production server with FCGI? The way I am understanding the 'Production' side of that picture is that the web server (eg. lighttpd) creates a single FCGI process. The FCGI process is actually the entry point of the Framework/Application which sets up Flup's WSGIServer, being the interface between FCGI and the Framework/Application? What I mean is, it is just the code that the web server loads to start with, example... from flup.server.fcgi import WSGIServer from app import application WSGIServer(application).run() ... Then for each HTTP request, Flup's WSGIServer creates a new thread to handle the request? As I've read elsewhere, "These days, FastCGI is never used directly. Just like mod_python it is only used for the deployment of WSGI applications." As far as I understand, the main (or only?) reasoning for this is because WSGI makes Python applications easier to deploy without having to worry about whether using FCGI/SCGI/CGI. What would be involved to run Python on the web using FCGI without WSGI? I can feel the flames already. This isn't the only reason I want to know, but one reason is that I want to use Python 3.1 and as I understand, this will have to wait for the WSGI 2.0 specification to ensure time isn't wasted. I apologize if the questions are ridiculous. I've just recently got into web programming and it seems that in order for me to use Python, I need a deep understanding of web servers, HTTP, FCGI, etc. I have more questions but they go more off topic, so I will save it for another thread, another day. I realize there is a large number of questions, so thanks for any help. -- http://mail.python.org/mailman/listinfo/python-list
