[Haskell-cafe] questions about network.curl/ web client programming

I'm learning both haskell and web programming as I go here, this question entails both. I'm writing a screen scraping program, and I'm at the point where I need to send certain data in the header. My question is, is that what method_HEADER is for? If so, could I see an example? If not, how does one go about shaping header data?
