A package for sending and receiving HTTP requests and responses, all implemented in Haskell (assuming you've already got a network stack to spare, via the network package!) The representation of content of in requests and responses is user-controllable, letting you pick a representation that fits your code better (e.g., use ByteStrings rather than the default Haskell Strings.) Example uses:

    do
      rsp <- Network.HTTP.simpleHTTP (getRequest "http://www.haskell.org/")
              -- fetch document and return it (as a 'String'.)
      fmap (take 100) (getResponseBody rsp)

    do
      rsp <- Network.Browser.browse $ do
               setAllowRedirects True -- handle HTTP redirects
               request $ getRequest "http://google.com/"
      fmap (take 100) (getResponseBody rsp)
