I want to have the guidelines for developing "Anonymous web site surfing".
I think I need to do the following process(roughly)
1) request a page to destination server
2) get the response
3) change those response as my own response
4) reply them to the user.

I have a little problem in step 2 and step 3.

I may be in wrong approach.
Pls let me have guidelines from you or let me know your idea.
