Building a proxy server

I am trying to build a HTTP proxy. The listening and accepting module is
already ready. I want to use libwww to get the request (data) from the
client, make some modification to it and send it to the destination server. 

 

1.	A live socket descriptor is given after a TCP connection from the
client is established.
2.	I need to get HTTP data from this descriptor using libwww. (I want
all the chunk handling and parsing of headers to be done by libwww)
3.	I need to parse this data, do some modification to it and send it to
the destination server.
4.	I don't need to tamper any HTTP headers only the data portion needs
to be modified.
5.	I also need to create my own request and send it to the destination
server with anything being sent by the client.

 

How do I use a live socket and bind it with libwww and get data to and from
client and server.

 

Any help will be highly appreciated.

 

And does anybody use libwww nowadays I don't seem to find any posts in the
mailing list. Has libwww become obsolete.
