help for GET config

[simbadda]

I want to ask, how to make the config so that in the header of the log looks "GET http://m.snaptu.com/psmobile/release HTTP/1.1" when I open the other sites.
and "host: m.snaptu.com"

My friend gave this hint:

Header = Replace (Header, "GET http://", "GET http://m.snaptu.com/psmobile/release")
Header = Replace (Header, "POST http://", "POST http://m.snaptu.com/psmobile/release")
Header = Replace (Header, "GET ftp", "GET http")
AddHttpHeader header = (Header, "Host", "m.snaptu.com")

but i dont understand

anyone can give me the config?
thanks, and i'm sorry for my english guys
