title: Block website access via browser
body: <p>I have a windows application which shows web page hosted in a website. Because of confidentiality, I don't want to show URL to the user. As this website is hosted on IIS and so user can access website directly through browser if he/she knows URL.</p>
  
  <p>How can I block access of website via browser but not through windows application? </p>
  
  <p>P.S. this website is third pary product hosted on my machine and I cannot do any code change into it.</p>
