append this.

var lURLToSend = "pageName.php" + "?r=" + new Date().getTime();
the getTime() method will provide an arbitrary, yet not
repeating value (milliseconds since January 1, 1970 00:00:00.000 UTC.)

That looks like an elegant way to handle it. Thanks.

IE caches all data retrieved via XmlHttp, just to clarify what the problem is.

A server-side solution would be to set the Cache-Control header for the page, assuming you're using a server-side technology to generate the data. In C# (ASP.NET), use the Response object:

With PHP, use the header() function:

It adds an extra line to your backend code, but it keeps your client-side code a bit cleaner.

I have the same problem...

FireFox works fine if I add the following header but IE not:
header("Cache-Control: no-cache");

then I have tried adding ALSO a query string:
var lURLToSend = "pageName.php" + "?r=" + new Date().getTime();
then IE works fine and FireFox not...

:(

I had the same problem particulary when using ajax to perform SQL Queries, checks would stop working after x amount of rapid clicks and my
inline editing needed a shift+refresh in IE in order for it to show the correct values.

Thanks to this thread i now use both the head technique in between </BODY> and </HTML> as well as sending all my http requests with unique url's thanks to Date().Time() and it's working like a charm.

Thanks guys!

Hi Guys,

Here is the elegant solution you're looking for - found it on Wikipedia, of all places. I just implemented it and it works like a charm.

req.open( "GET", "xmlprovider.aspx" );
req.setRequestHeader( "If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT" );
req.send( null );
