Modification of the server http responses on the client site

Question

I want to modify all http responses (http pages): add some js into server responses before it will appears in browser.

For example "Ad muncher" is doing it. It add js that removes ad from all pages.

How can I do it?

I known only 1 solution: WFP (Windows Filtering Platform), but it is available only from windows vista.

P.S: I don't want to use proxy server for this purpose. Because I want the cross-browser solution, I don't want to let user change any browser settings. Also user could work througth some other proxy...

Thanks for any help.

Take a look at Komodia's Redirector1. It uses Winsock LSP. And it has WFP module for Windows 7 and 8.
