Question

I am trying to create a login system for my iPhone application. My login system is not an ordinary one. Here is what I want the iphone to do.

First of all I will post to a website
“https://www.example.com/login”
my username and password.
If login is achieved (i.e. username and password are correct), it will redirect me to
“https://www.example.com/login/success”
else it will redirect me to
“https://www.example.com/login/retry”.
I know it sounds strange but thats the way it works. By the way my application is programmed using Objective-C.
So what I want from the login system is to detect the address of the redirected site and if it is the success one, it will allow me to view the rest of the application.

Can I do that login system on iOS? Do you have any idea about that?

The NSHTTPURLResponse class has a method allHeaderFields that you can use to pull out the Location header. Be aware that header names are case-insensitive.
