Make Google Chrome report it's running on a different OS

Question

I'm running Chrome on Linux and I want to make it report to the website I'm developing as it's running on a Windows machine and on a Mac OS, for testing purposes. I'm not talking just about the User Agent, if you go to about:version there is a field which says OS:. I want to fool the website as much as I can, how is it possible?

Answer 1

Not too sure if you can do this, but I'd start with looking at Fiddler (http://fiddler2.com/) and then intercepting the calls and modifying the relevant fields.
