Connect to internet through login wifi automatically.

At my uni campus they have wifi everywhere, but when you connect to it (which my mac does automatically) you have to go in through a login page before you can use it.

How can i get it to login once it connects to the wifi (i do use other wifi connections which dont require login). There is no wifi password (just the login page).

Other than for ease of use, the other reason i am doing this is because i am setting up my cam to take pictures of a thief if my mac were to be stolen (then upload to ftp). The more auto connected internet - the better.

If this requires automator or applescript i should be ok, but make it obvious.

thanks
