Advice for Python and Web Server/Services?

I have recently discovered Python and like it quite a bit. I would like to
use it on a new project I am starting. 

The project will gather data from several web services and present the
collected data to browser users through a web server.

So basically I need a full-time web server and a separate way to poll web
services for their data. There is no database involved.

The problem is that I have tried several Python web servers (CherryPy,
Karrigell, etc) and they all have problems getting out through my Comcast
cable modem. There is a 3 second pause every 10th file. Never the 9th or
11th, but always the 10th file. 

I thought maybe Comcast was limiting incomming HTTP but Apache does not do
this so I'm stumped as to why it is happening with the Python servers. All
servers work fine over the LAN.

Anyway, I wanted to get some advice on what type of setup would be best
for this using Apache. The web service polling needs to be going all the
time so a straight CGI-type thing is not an option. 

I've looked in to fastcgi and mod_python but I'm not sure either is what I
need. What I want is for my Python program to be polling the web
services 24/7 and Apache to serve static pages by itself but call
a function in my already running Python program for files with a certain
extension (.xml for example).

Have any of you done something like this before?

Ideally, I'd like to figure out why the Python servers are having
problems. This is a very low volume system so straight Python would be
great if I can get it working.

Thanks for any advice you can give.
