Loading ajax content - caching woes

Hi all,

I've having an issue with cached content loaded by Ajax.

I'm using jQuery and have disabled browser caching for jQuery ajax requests. I've disabled the SS cache (with HTTP::set_cache_age set to 0). I have cleared the browser cache and rebuilt/flushed. Despite this, content loaded via ajax seems to be coming from a cache. I have to append the ajax query with ?flush=1 to force the response to be updated.

Anyone got a better way?

By the way, the Wiki says that:

"Ajax requests are never cached."

But that is not what I'm seeing.

Are you using Internet Explorer? According to this page:

...IE caches the requests:

Note: Keep in mind that Internet Explorer caches the loaded file, so you should pass some extra random GET parameter to prevent caching if you plan to call this function more than once

Even if not you could try appending a random GET string to the URL you're calling via AJAX and see if that helps.

Thanks David, that occurred to me, but I didn't think it would be necessary. I was using FF3 to see the requests.

No worries - did that fix it or was there some other solution?

Yes, it seems to have done the trick.

var obj = jQuery.parseJSON(vystup);

Hi, would you be able to post some example of your ajax code. I am wanting to do a something like this:

$('input.action').click(function() {
$(this).append('<img src="images/ajax-loader.gif" class="loaderIcon" alt="Loading..." />');

var Name = $('input#name').val();
var Email = $('input#email').val();
var Comments = $('textarea#comments').val();

type: 'post',
url: 'sendEmail.php',
data: 'Name=' + Name + '&Email=' + Email + '&Comments=' + Comments,

success: function(results) {
}); // end ajax

Thanks for any help you can advice me on.
