ET, which i assume you mean wolfenstein enemy territory, which uses UDP to return info on servers. You need to use /sockudp and on udpread.
The client sends this to the server to get info: ÿÿÿÿgetinfo xxx

It'd be much easier to just use sockets to connect to this page:

http://enemy-territory.4players.de:1041/...lt;port>

Replace <serverip> with the server ip and <port> with its port.

Thats the main page btw.
