title: How to BASE64 encode URLs?
body: <p>I was browsing torrents at KickAssTorrents.com, when I visit a link it is encoded in the url in a different way;</p>
  
  <p>for example (IMDb link): <a href="http://kat.ph/account/confirm/url/aHR0cDovL3d3dy5pbWRiLmNvbS90aXRsZS90dDA0MDE3Mjk=/" rel="nofollow">http://kat.ph/account/confirm/url/aHR0cDovL3d3dy5pbWRiLmNvbS90aXRsZS90dDA0MDE3Mjk=/</a></p>
  
  <p>Now, when I change a character something changes in the link and I want to know how to do this in C# or jQuery ?!</p>
