[isf-wifidog] Wifidog, portal page and Apple auto-login

[Geneviève Bastien]

Thanks for the answer, but that is not the issue.  It is more Apple 
products bypassing the portal page, the whole login process is all fine.

I found this: 
http://blogs.oucs.ox.ac.uk/networks/2009/10/12/fixing-the-iphone-os-wifi-auto-login-problem/  
Which may suggest that we could bypass the auto-login feature from the 
server side by answering the request with the expected output.  The user 
will then have to open a browser page to see the actual login and portal 
pages.
