We designed a website about 6 months ago that has just had a minor tweek done to it, change of graphics and text in places. The client has had a look at the new site on one machine and all is fine, had a look on another machine and some of the graphics have not changed. I have got him to delete his cache and to set the check for newer versions to every visit to the page, but it is still the same. We have got rollovers, when he rolls over some he gets the old button instead of the new one. If this makes sense, does anyone have any suggestions ? I was thinking that maybe it is an ISP caching issue. what you think ?
