title: Remove additional slashes from URL
body: <p>In <code>ASP.Net</code> it is posible to get same content from almost equal pages by URLs like 
  <code>localhost:9000/Index.aspx</code> and <code>localhost:9000//Index.aspx</code> or even <code>localhost:9000///Index.aspx</code></p>
  
  <p>But it isn't looks good for me. </p>
  
  <p>How can i remove this additional slashes before user go to some page and in what place? </p>
