Yes, but not only 3 lines... a GET request needs to include some other information, like "Connection" and "Host" to avoid problems (read here to know why).

For example,
Code:
alias ChecaWeb sockopen ChecaWeb www.indiasex.com 80
 
On *:sockopen:ChecaWeb:{
  sockwrite -n ChecaWeb GET /members HTTP/1.0
  sockwrite -n ChecaWeb Host: www.indiasex.com
  sockwrite -n ChecaWeb Connection: close
  sockwrite -n ChecaWeb Authorization: Basic $encode(user:pass, m)
  sockwrite -n ChecaWeb
}
 
On *:sockread:ChecaWeb:{
  var %s
  sockread %s
  echo -s -> %s
}

Paste it into the remote and type /checaweb to begin. Remember to change the user/pass to the real ones.
