Does anyone know a pattern in which I can do this easily?

Don't use hGetContents on a socket. That's asking for trouble.

Can you please explain why? What is a more easier method to spool your HTTP post data to a file than: Bs.hGetContens sock >>= Bs.hPut fd ?

Use hGetContents either NEVER (easy option) or only on throwaway handles/files which won't be used again.

My sockets will be thrown away eventually. Isn't anything? I can imagine that this can be a problem when using Keep-Alive connections - or alike - but that is a whole different story.

Thanks, Sebas.
