My solution is now up running and people complain about two things when they set up the "agent".

1) The popup boxes to fill out closes, if you switch tab to copy the key.. People seldom can remember the key :)

2) They all complain about the URL and KEY being stored in a cookie.
  • a) They use a lot of different devices.
  • b) Their work cleans cookies on restart/reboot.

Would it be possible to store the URL and KEY on the server side instead? Would help the end users a lot..
