title: Asp.net mvc3 web site extension
body: <p>Want to implement this feature but how?</p>
  <p>We know that stack overflow has been written in asp.net mvc3 from <a href="https://blog.stackoverflow.com/2008/09/what-was-stack-overflow-built-with/">what was stack overflow built with?</a> .</p>
  <p>When i am here i have never noticed .aspx extension in URL, but it should be there as all asp.net web site has it. it may be the silly point to ask. but i am very curious to know how to exactly hide the extension for asp.net web site.</p>
