[Web-SIG] CGI HTTP Proxy

[Eric Radman]

Before mod_wsgi exists I think it's needful to have an efficient way to
proxy http requests and responses through CGI. Is there a small app
written in C that we can use to call a running WSGI Server? I found one
old app that would probably do the job if it were updated:

http://www.leerssen.com/cgiproxy.html

He's calling this a CGI proxy, but it's really a HTTP proxy, which is
what we need since the WSGI Server is a true HTTP server itself.

On dedicated servers with multiple IP addresses where I have
administrative control over the web server and DNS I can simply map
hostnames for each WSGI application like this:

 www.mycompany.com (10.0.0.100) > HTTP Server
app1.mycompany.com (10.0.0.101) > WSGI Server <> WSGI App 1
app2.mycompany.com (10.0.0.101) > WSGI Server <> WSGI App 2

But in most virtual-hosting environments there needs to be a way to map
HTTP requests to WSGI servers behind the HTTP Server listening on the
one public IPv4 address:

*.mycompany.com/      (0.0.0.0) > HTTP Server
*.mycompany.com/app1/ (0.0.0.0) > HTTP Server > WSGI Server <> WSGI App 1
*.mycompany.com/app2/ (0.0.0.0) > HTTP Server > WSGI Server <> WSGI App 2

What's the best way to deploy multiple applications along side a HTTP
server serving static content?
