Webmaster Forum / HTML, CSS, Scripts / JavaScript / March 2005

I have a situation where I'm using XmlHttpRequests to update some data
in a table every few seconds. The script that executes when the data
comes into the browser checks to see if the data has changed compared
to that currently displayed - if it hasn't changed, it does not update
anything.

I'm having a problem on ONE single computer in that changed data is
being sent but the script doesn't see it. I found that if I cleared
the browser cache, then it worked as expected - once - then it fails
again.

This HttpRequest contains only a small data string - it's not an
entire page. Is there a way to get the browser to use the lastest data
and not the cached data?
