Repeated port in redirectURL parameter when running under IIS

[morcs]

I'm running a test client under IIS at https://localhost:44396/.

When the code redirects to the identity provider - it is adding the port number twice in the redirectURL (i.e. https://localhost:44396:44396/)

I've tracked this down to the use of _SERVER["HTTP_HOST"], which in my case includes the port.

I've modified the code to strip the port if present. I'll try and send a pull request with this fix in.
