external link does not work in IIS express. How do I get links to reach internet? : Ok so when you click a link in my web app it just adds to the URL to the end. like so "http://localhost:8080/http//:www.youtube.com". I'm using visual studio .netto make web rest APIs. The web app lunches on IIS express 10. the home page URL is "http://localhost:8080/index.html".
