title: Incorrect path url for a jquery ajax request
body: <p>I have a very simple question. I would like to proceed  to a jquery $.ajax request. I have some trouble with the 'url' right formatting. My index.php is in some folder, call it 'public'. In this folder, I have also my js files. Sharing the same level of the tree than 'public', I have a folder called 'classes' where I put my php files. I want to make an ajax request from an html page which is in the publuc folder. So for the 'url' data of the jquery ajax method, I put '../classes/ajax.php'</p>
  
  <p>But it didn't work. Do I have a path syntax problem?</p>
