Parsing a http request

Question

i got to parse every http request from the browser in the client machine as a part of my project. i had already posted this query in the forum and got the reply as follows......
*"First you need to put your code between the browser and the network.*
*So your code needs to open a socket on port 80 (the standard http port) and a server socket at the proxy port - you can choose any post but proxies often use 8080.*
*Configure your browser to connect via a proxt using localhost:8080.*
*Then you code has to listen for requests on the server socket and pass them on to port 80, and route the responses back.*
*Once you have that going, you will be able to start to parse the requests."*
But im already connected in a LAN which passes each request through a proxy...... so what should i do now to catch the http requests.......

Answer 1

There can be multiple proxies. Setup your new proxy server to use the existing proxy server, then reconfigure your browser to use the new proxy server.
Also, rather than writing your own proxy server, you should look at downloading an existing one. I believe Apache can be set up as a proxy server. Also I'll bet there are plenty of lightweight proxy servers written in a variety of languages on sourceforge.net. I think there may be one in the Python standard library.
