On top of my head: lhttpc (Two branches: Fred Hebert, and one by Erlang Solutions Ltd.), gun (Loïc Hoguin), ibrowse (Chandrashekhar Mullaparthi), fusco (Diana Corbacho) and probably a couple I've forgotten. Different implementations enjoy different properties, so picking the one for your project may be something that takes a little time.
