I emailed you detailed info. The symptom of the bug would be, that data of one video-request will receive the storage key of the request for another video, and vice versa. This can only occur, when you have 2 or more users accessing yt the same time. Or one user watching yt in 2 browser windows simultaneously. So, the more users you have active, the higher the probability, that it might show up. I also sent you a suggestion, how to reduce the probability of the bug to show up. Unfortunately, I do not see the chance for a fool-proof solution. Unless, the rewriter has access to the header data of the GET. AFAIK, this is not possible. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Re-squid-3-Head-storeid-tp4659552p4659585.html Sent from the Squid - Users mailing list archive at Nabble.com.
