"redirecting" a browser to a different IP

How is this done? A good example is at many public Wireless Hot Spot is to aquire an IP and then fire up your browser. No matter what your start page is the browser goes to the providers Web page to login, signup or whatever. Is this done via software or hardware?

Thanks,

Diego

Re: "redirecting" a browser to a different IP

They use the authentication proxy server to force the authentication. Once you get the ip and fire up the browser, request to the homepage is intercepted by the router/firewall in the middle and the user is forced to a web page for authorization.

Here is the url which explains that

This is usually done by intercepting the HTTP request and returning whatever page is specified by the service provider. No special hardware is required - this is done via software.
