How to open a URL containing a port on Windows Phone?

Question

Opening a link like http://portquiz.net:8080/ results in the following error message on Windows Phone's Internet Explorer: We're having trouble displaying this page.

Happens both on Windows Phone 8.0 and 8.1. How can I go to a website that contains a port number as port of its URL? The question at Windows Phone: possible to open URLs with :port? suggests that its enough to include the http:// prefix, but that does not help in my case.

Answer 1

Can confirm that URLs with ports do work. This has been known for a while, and one of the great examples that actually uses this capability to install a third-party test certificate is Fiddler.
