title: Send AJAX request to .aspx page and return JSON
body: <p>I know that it is possible to send an AJAX request to an <code>.asmx</code> page. And I also know that an <code>.asmx</code> page handles an AJAX request via a web method.</p>
  
  <p>Is it also possible to send an AJAX request to an <code>.aspx</code> page? If so, does an <code>.aspx</code> page also handle an AJAX request via a web method? Note that I would like to return a JSON response from the <code>.aspx</code> page. Is this possible?</p>
