Strange need - "Repeater" appliation

I need to create a simple app that works like a radio repeater, in that is simply passes information it receives through to another script, in both directions. In other words, a remote application located at www.domain.com/app.php accepts variable1, variable2, and variable3, and returns a response based on that information. I want to put a "repeater app" in the middle of the browser and the url above, so information is passed to www.mydomain.com/process.php, and is not changed at all, but is sent to www.domain.com/app.php, and the response from www.domain.com/app.php is sent back to www.mydomain.com/process.php, so the results of sending the same information to either url will be exactly the same. I'm not trying to do packet sniffing or anything, just trying to "mask" a url. It would be nice if I could pass cookies through as well. Any help, resources, ideas, etc appreciated.
