I am puzzled by two things:

  0xd 0xa is CR LF.  Something like this seems sort of expected in these
  sorts of protocols, but I'm really not clear on the details.   It
  could be good to chase down the rules for these sorts of
  looking-like-http messages.

  The code uses strstr which is supposed to find a substring, perhaps
  for this very reason.
