Is this something like what you're looking for?

1> http:request_sync(get,{"http://www.erlang.org/foo",[]}).
{404,
 [{'Transfer-Encoding',"chunked"},
  {'Content-Type',"text/html"},
  {'Date',"Wed, 09 Apr 2003 01:43:27 GMT"},
  {'Server',"Apache/1.3.9 (Unix)"}],
 "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML

It doesn't look like the http client module is documented yet.
