Urgent : help needed on web server implemenation

Hi,

I am trying to implement a web server in C++.
This is my first attempt at network programming
so I am having a loot of trouble identifying the
right classes, their jobs and their interactions.
The aim is to make the web-server extensible, so
that it serves static pages now, but can be extended
to service dynamic pages later on.

I request anyone who has had some experience in this
to help me out in this regard asap.

Regards
Santhosh
