I work for a dealership and recently the manufacturer began embedding our dealer number as a watermark in PDFs via a parameter in the URL. Ever since they started doing this Adobe Reader is reporting that the PDFs are corrupt when trying to open them. If we bypass Squid then there's no issue and the PDFs open fine. I've tried adding a no-cache acl but that didn't help. I've searched the list and Googled the web but haven't found a solution. Were currently running Squid 2.5 Stable 11. Any ideas of how I can solve this? Sincerely, Louis Baumann
