title: jquery ajax GET request executing twice
body: <p>I have the following ajax request that is executed at a click of a button:</p>
  
  <pre><code>&lt;a href="javascript:test()"&gt;&lt;img src="css/images/test.png"&gt;&lt;/a&gt;
  
  function test(){
      console.debug("*");
  
      $.ajax({
          type: "GET",
          dataType: "json",
          url: '/path/to/url',
          success: function(data){
              console.debug("**");
          }, 
          error: function(jqXHR, status, error){
              console.debug("*** " + status + " : " + error + " : " + jqXHR.status);
          },
          cache: false
      });
  }
  </code></pre>
  
  <p>The request response takes approximately 30 seconds to return. However, the request is received and executed by the server twice as can be seen by the apache logs. The timestamp of the requests are 30 seconds apart but the request is identical (e.g ?_=1363692320782). The click response function is called once and the error callback is invoked once (exactly 60 seconds after initial request), although the apache response is a 200.</p>
  
  <p>This problem has been reproduced in a Samsung Galaxy S2, android version 2.3.5 in a phonegap application.</p>
  
  <p><strong>UPDATE - adding Apache log entries from comment below</strong></p>

  <p><strong>UPDATE - adb logcat</strong></p>
  
  <pre><code>I/Web Console(16747): * at file:///android_asset/www/js/mobile.js:1769

  <p><strong>UPDATE - TCP/IP monitor</strong></p>
  
  <p>Putting the requests through a TCP/IP monitor shows both requests being sent with a 200 response for both.</p>
