[Haskell-cafe] Question about fastcgi

[Mauricio]

Hi,

I'm learnng to use fastcgi and, reading the examples,
I see the main "loop" is like this:

main = runFastCGI my_work

However, isn't a fastcgi program supposed to choose
a port where to listen to calls? For instance, in this
C example:

xzdev.com/nginx_fastcgi.html

doesn't the line

listen_socket = FCGX_OpenSocket(":8002", 2000);

says it's listening to port 8002? I read the code
for fastcgi, from hackage, and I can't find anything
related to ports like, for instance, a default port.
Am I understanding something the wrong way?

Thanks,
Maurício
