title: MVC3 generic handler (.ashx) for Images resizing (Need clean URL)
body: <p>I have a generic handler (.ashx) in asp.net mvc3 web application. I use it to resize and cache images. but my Url is not clean (<a href="http://www.example.com/Thumb.ashx?img=someimage.jpg" rel="nofollow">http://www.example.com/Thumb.ashx?img=someimage.jpg</a>) I want to make it clean like <a href="http://www.example.com/Thumb/someimage.jpg" rel="nofollow">http://www.example.com/Thumb/someimage.jpg</a>
  how can I do it?</p>
  
  <p>Can I maproute in global.asax, it yes then how? or should I use IIS 7 URL rewrite?</p>
  
  <p>I appreciate any help, Thanks</p>
