Web auth (redirect) doesn't work when client uses a https url: CSCar04580 Bug
Monday, July 23, 2012 at 12:22PM Issues with your Cisco Wireless Guest Network not doing a web redirect ?
This is very good to know, incase you get calls that your wireless guest network is broken. The WLC will not redirect 
HTTPS urls.
Assume for a moment your guest has a browser home page that is https:// (443) or he / she attempts to open a https:// page, prior to the AUP. The user is expecting to get redirected, but nothing happens.
The Guest will sit and spin giving the impression the guest network is not working properly, but in fact the WLC is not redirecting HTTPS traffic, only HTTP traffic to the AUP.
CSCar04580 Bug Details
| web auth (redirect) doesn't work when client users a https url | ||
| Symptom: A client whose home page is an HTTPS (HTTP over SSL, port 443) one will never be redirected by Web Auth to the web authentication dialog. Therefore, such a client will not know to authenticate, and will fail to connect to the network. Workaround: The client should attempt to open any HTTP (port 80) web page. |

ITs also worth noting, at least in 6.0, if you want to enable port 80 redirect, you have to turn off all secure communication to your WLC. This is really annoying, and I hope Cisco fixes this soon. To my knowledge, they have not fixed this in 7.0.
I remember this being in documentation since at least version 4.2 of WLC code. Check the Wireless LAN Controller Configuration Guide for release version 4.2. It's in there.

I find it interesting they call this a bug, rather then a feature of sorts .. :)
