title: ajax call handling on asp.net serverside
body: <p>I'm working on an asp.net project based on asp.net AJAX but we get more and more client side calls using jquery ($.ajax) and get json or html return. I'm wondering what is the best way to handle these calls on the server side, in the same webform, or use a specific http handler, or even web service? can somebody share the experience or best practice?
  thanks.</p>
