The AP3825i can be configured through Wireless Controller or SSH or serial port.
So you can install on some computer HTTP-to-SSH proxy. Then you will be able to use HTTP and the AP will be configured through SSH.
I believe there are also some terminal servers available on the market = you will connect to the terminal server over http and you will see the serial port output in your browser.
Good luck
