Here's the situation: I am trying to show a demo for a chrome extension on MAC, and due to chrome's security policies it's only allowed to use HTTP connections to localhost. The test server I have is on another machine, and cannot be run easily on MAC. So I want a simple program running on my MAC that listens to requests on a specific port, forwards it to another machine, gets the response from there and sends it to the original requester.
I just want to get something working quickly, dont really care about features, efficiency etc. What should I do? Should I go for a proxy (and if yes, which one?) or would something easier do?
