We need to build a web application that another company will use. They will link to the site directly from their own intranet. What I want to know is if there is a way that our web site can confirm that the user is coming from their intranet and not typing the url directly into a browser? I am exploring this to see if there is a way to not let users access the site unless they are originating from their company intranet. (Only one company will be using the site.) Thanks.
