Sac> Otherwise, someone could simply spoof you by copying the value. so it can work for example like this: Client -> Server -- wants connect Server -> Client -- sends session ID (SID) Client -> Server -- sends SID, checksum/secure join SID "mypass" Server compares if (checksum/secure join SID "mypass") is correct. This is good way how to prevent sending pure passwords thru web. This is trivial scenario. You can make it more difficult as well but than be careful to stay able to connect to your app:)) -- Best regards, rebOldes -----------------[ ]
