I am getting following error

Failed to load resource: the server responded with a status of 412 (Precondition Failed)

while I try to fetch data from a text file using `$.post`
On first try web page works fine and data is loaded from file but when I refresh it is not loaded sometimes.When I deleted cache and try again it was loaded successfully.But still I think this problem is not because of cache only.First time when I loaded the page error was there showing in JS console.I am using Google Chrome.

<body>

      <div onclick="fetch_data()">click me</div>
      <h1 class="result"></h1>

  </body>

  <script type="text/javascript">
      function fetch_data()
          {
              $.post('sometext.txt', function(data)
              {
                  $('.result').html(data);
              });
          }
  </script>

I suggest running a utility called Fiddler to inspect the HTTP traffic between your computer and the client. It sounds like a networking issue.
