We need someone who can fix one small bug. We are running a banner rotator(swf) that runs through .xml files and the problem is that when we change graphic slides in it each month the browsers keep showing the old files. The only thing that solves the problem is if user clears the cache manually in his browser but obviously our users are not doing this. So we need a solution that will cause the site to clear cache and not show the old files when new files are uploaded.
More details on PM.
