Hello,

A browser window pops up everytime an iOS device (iPad, iPhone, etc) connects to the hotspot.

So it works now like this:
User click on Wifi hotspot connection->it stays on 3G connection (iPhone)-> popup open->login in popup->There is a Wifi hotspot connection after complete login.

To prevent this, there is only one thing I can do. Whitelist http://www.apple.com so the *OS will think that users will have full internet access* and the popup won't appear automatically.

But this is what i want
User click on Wifi hotspot connection->*it give Wifi hotspot connection* (OS will think that users will have full internet access)-> popup open->In the popup i can display some text that user have to login to open his webrowser->user close pop up and go to webbrowser and get redirect to my hotspot login page.

Can someone tell me how to do that?

Don't think that is possible, the popup only appears when IOS believes it can't reach the Internet.
