I am doing a site where an excell sheet listing yesterday's events is uploaded daily. I name the file the same I just overwrite it. The problem is that when you click to open the excel spreadsheet is that it always opens the first version that you have looked at. That is if you look at the events for feb 6. Somebody updates it for the seventh. The next time you look at it you still the excel sheet from Feb 6. But if you go from a new computer you get Feb 7th. However when you look at the copy that is on the server it the Feb 7th. So I guess my question is how do you make sure that the copy that is loaded in the browser is the most recent.
