when I try to access to login page by mail.google.com (HTTPS) explorer don’t redirect me to login page! But If I try with normal page HTTP the explorer redirect me to login page of hotspot, then I login and I can access to mail.google.com HTTPS.
When my users before login to hotspot they connect to www.google.com and the login page apear.. but when they put https page like mail.google.com the login page not appear.
That is because you cannot redirect an HTTPS session to a HTTP session. They are different protocols and use different ports. This is the same for every gateway/hotspot out there.
Since we don’t use HTTPS on our initial login pages, I’m not sure if you run an HTTPS version of your login page if you will or won’t be able to redirect HTTPS users to that.
