  <p><code>request failed: URI too long (longer than 8190)</code></p>
  
  <p>I've seen other posts on StackOverflow for this one. Those posts recommend:</p>
  
  <ul>
  <li>Not changing Apache settings (agree)</li>
  <li>Using post, not get</li>
  <li>Not using <code>jsonp</code> with post</li>
  </ul>
  
  <p>I'm using jQuery's AJAX to POST:</p>
  
  <pre><code>    $.ajax({
          url: "test.php",
          dataType: "json",
          data: paras,
          type: "POST",
          success: function(ret){callback(ret);}
      });
  </code></pre>
  
  <p>It's my impression you can use json just not jsonp. Correct? If so, why might I still be getting the error?</p>
