I'm trying to get an mIRC bot to log into a forum, but so far haven't succeeded.

What I have so far:

Code:
alias forum {
  sockopen forum forum.com 80
}

on *:sockopen:forum:{ 
  write -c forum.html
  sockwrite -n $sockname GET / HTTP/1.1
  sockwrite -n $sockname Host: $+(forum.com,$crlf, $crlf)
}

on *:sockread:forum:{
  if ($sockerr) {
    echo -a Error.
    halt
  }
  else {
    var %temptext
    sockread %temptext
    write forum.html %temptext
  }
}


I somehow need to send it the cookies, so it will recognize me as logged in.
I've tried things like: sockwrire -n $sokname Cookie: etc, but it didn't work.
