Hi there!

I know there's a problem with Internet Explorer caching AJAX request so that, for example, my dynamic gauge chart shows always the data of the first AJAX call, while with Mozilla, Chrome and other I can see the values changing.

Is there a way to disable AJAX request caching in Explorer or tell RGraph not to cache the requests?

Thanks in advance

Hi there,

If there is then you'll probably find it in the options - try disabling caching entirely. You could also try appending some random query string data to your request URL like this:


Or another - more involved - method would be to put the random string at the front of the request like this:


And use URL rewriting to change the URL to getData.html. Though try the query string option first as it's easiest.
