Thanks for your reply. The unique links are generated properly by LaserFiche and therefore contain the correct DBID for each document (or folder) in the URL/URI. It's just that some users report that when they click from among various links (especially when those links point to different DBs) the browser opens a folder/file originating from a DB that had been opened previously, In other words, it's as if the browser loads from cache rather than from the link that had actually been clicked. To my knowledge, we aren't using any proxy servers in between browser and Laserfiche/web servers. I've not been able to reproduce the quirky "error", but I can contact the end-user to see whether the problem persists. Thanks again! If you have any other ideas, please share.
