POajax call to servlet puzzler

Body
copied!<p>Greetings!</p> <p>I'm having a problem getting a text value of a captcha from a servlet through ajax call. </p> <p>When my captcha gets created, its text value is written to session, but after refreshing the image itself though ajax call, I only get one old value of the text.</p> <p>Refreshing the image itself works ok, but I'm stuck getting the correct values from the session on subsequent call.</p> <p>On page reload I get both the new image and its new text value, no joy with ajax though.</p> <p>This works great for the image refresh:</p> <pre><code>$("#asos").attr("src", "/ImageServlet?="+((new Date()).getTime()) ) </code></pre> <p>This call to another method to get text value gives me old stuff:</p> <pre><code> $.ajax({ url:"checkCaptcha", type:"GET", cache: false, success: function( data) { alert(data); } }); </code></pre> <p>Any feedback will be appreciated.</p> <p>ps: here's the meat of the method getting the call:</p> <pre><code> PrintWriter out = response.getWriter(); response.setContentType("text/html"); response.setDateHeader("Expires", 0 ); // Set standard HTTP/1.1 no-cache headers. response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate"); // Set IE extended HTTP/1.1 no-cache headers (use addHeader). response.addHeader("Cache-Control", "post-check=0, pre-check=0"); // Set standard HTTP/1.0 no-cache header. response.setHeader("Pragma", "no-cache"); out.print( request.getSession( ).getAttribute("randomPixValue") ); out.close(); </code></pre>
