Okay this is probably going to be a really complicated question, but maybe someone can give me an idea on how this works.
I travel as part of my job. When I stay at a hotel and try to open a browser to surf, I get redirected to the hotels portal rather than my home page. Typically, there is an authentication process, but not always. How is the redirect accomplished?
The reason I am asking is that we are working on a mobile application that will reside on an unsecure wireless network. We can either enable security on the router (really big headache because this wireless router will be sitting on a customer network and would then require a VPN to cross networks) or run open with a redirect to our webpage to authenticate and open access to the internet. Our application is web based and the mobile app is really nothing more that some forms that submit the data to our web site. Our customer wouldn't be willing to spend the resource hours to set up the VPN access at all locations across the US, so we thought running an unsecure wireless connection that required some sort of portal security might be a better solutions.
