HTTP Protocol Working

Question

I need to ask a question about HTTP protocol. I am trying to develop a sandbox (web browser) where any one can surf the website with different identities. Different identity means that on each request to a page will be from different IP address.

Now I don't know how scripts on web servers check the IP address of the one who generated the request. This is possible and I am aware of this. But I need to know whether this is HTTP request header that has the IP address or something else.

Simply speaking, I want to fool the websites. :)

Answer 1

You need to read up on the layers that build up a network from the wires[1] to the application. I think you'll find the the IP address is known long before HTTP gets involved.

See http://en.wikipedia.org/wiki/OSI_model

[1] or photons, or radio waves, or smoke signals...

Answer 2

Uh, the IP address is provided EVERY time you connect to ANYTHING. It has nothing to do with http headers.

See IPv4 -> packet structure -> header
