Arduino and Wifly shield problem connecting to network

I am using an Arduino UNO Board and a WiFly shield. Right now, I’m using the serial monitor of the Arduino to configure the WiFly shield. I have a major problem because I can’t get past the network security of my university’s wireless network. I am able to associate, however, whenever I try to send data anywhere, I can’t because the network is set up so that when you try to access the a webpage, you’re redirected to a webpage where you have to enter a username and password to use the Internet. I can’t figure out how to get around this, since I can’t click in a box and fill in that information with an arduino board. Is there anyway to send this data from the WiFly shield? I’d appreciate any help.
