Hi Pavel, Here size of the big file is not an issue. If I am playing the same file using windows media player, it's getting cached. I have tried the method suggested by you. But those messages are not so clear to me. I am posting those messages below. Please have a look and tell if you can make out something. 2013/09/17 10:44:02| storeClientCopy: 3AC24A8523C630E0017D538FCF058E6D, seen 1893429, want 1893429, size 4096, cb 0x423170, cbdata 0x16d8fc48 2013/09/17 10:44:02| storeClientCopy2: 3AC24A8523C630E0017D538FCF058E6D 2013/09/17 10:44:02| storeClientCopy3: Copying from memory 2013/09/17 10:44:02| storeClientCopy: 3AC24A8523C630E0017D538FCF058E6D, seen 1895953, want 1895953, size 4096, cb 0x423170, cbdata 0x16d8fc48 2013/09/17 10:44:02| storeClientCopy2: 3AC24A8523C630E0017D538FCF058E6D 2013/09/17 10:44:02| storeClientCopy3: Waiting for more 2013/09/17 10:44:05| storeClientUnregister: called for '3AC24A8523C630E0017D538FCF058E6D' 2013/09/17 10:44:05| storeClientUnregister: store_client for http://10.102.78.163/Police_122.wmv?MSWMExt=.asf has a callback 2013/09/17 10:44:05| storeSwapOutMaintainMemObject: lowest_offset = 1895954 2013/09/17 10:44:05| storePendingNClients: returning 0 2013/09/17 10:44:05| CheckQuickAbort2: entry=0x16f3e930, mem=0x16cdbc90 2013/09/17 10:44:05| CheckQuickAbort2: YES bad content length 2013/09/17 10:44:05| storeAbort: 3AC24A8523C630E0017D538FCF058E6D 2013/09/17 10:44:05| storeLockObject: (store.c:1397): key '3AC24A8523C630E0017D538FCF058E6D' count=6 2013/09/17 10:44:05| storeExpireNow: '3AC24A8523C630E0017D538FCF058E6D' 2013/09/17 10:44:05| storeReleaseRequest: '3AC24A8523C630E0017D538FCF058E6D' 2013/09/17 10:44:05| storeDirSwapLog: SWAP_LOG_DEL 3AC24A8523C630E0017D538FCF058E6D 0 0000031E 2013/09/17 10:44:05| storeKeyPrivate: GET http://10.102.78.163/Police_122.wmv?MSWMExt=.asf 2013/09/17 10:44:05| storeHashInsert: Inserting Entry 0x16f3e930 key 'D6568710A5766951D833459D605758CE' 2013/09/17 10:44:05| InvokeHandlers: D6568710A5766951D833459D605758CE 2013/09/17 10:44:05| storeSwapOutFileClose: D6568710A5766951D833459D605758CE 2013/09/17 10:44:05| storeSwapOutFileClose: sio = 0x16e04518 2013/09/17 10:44:05| storeSwapOutFileClosed: SwapOut complete: 'http://10.102.78.163/Police_122.wmv?MSWMExt=.asf' to 0, 0000031E 2013/09/17 10:44:05| storeCheckCachable: NO: release requested 2013/09/17 10:44:05| storeSwapOutFileClosed: store_swapout.c:371 2013/09/17 10:44:05| storeSwapOutMaintainMemObject: lowest_offset = 1895954 2013/09/17 10:44:05| storeUnlockObject: (store_swapout.c:375): key 'D6568710A5766951D833459D605758CE' count=5 2013/09/17 10:44:05| storeUnlockObject: (store.c:1422): key 'D6568710A5766951D833459D605758CE' count=4 2013/09/17 10:44:05| storeUnlockObject: (store_client.c:575): key 'D6568710A5766951D833459D605758CE' count=3 2013/09/17 10:44:05| storeUnlockObject: (client_side.c:1271): key 'D6568710A5766951D833459D605758CE' count=2 2013/09/17 10:44:05| storePendingNClients: returning 0 2013/09/17 10:44:05| storeUnlockObject: (forward.c:119): key 'D6568710A5766951D833459D605758CE' count=1 2013/09/17 10:44:05| storeUnlockObject: (http.c:75): key 'D6568710A5766951D833459D605758CE' count=0 2013/09/17 10:44:05| storePendingNClients: returning 0 2013/09/17 10:44:05| storeRelease: Releasing: 'D6568710A5766951D833459D605758CE' 2013/09/17 10:44:05| destroy_StoreEntry: destroying 0x16f3e930 2013/09/17 10:44:05| ctx: enter level 0: 'http://10.102.78.163/Police_122.wmv?MSWMExt=.asf' 2013/09/17 10:44:05| destroy_MemObject: destroying 0x16cdbc90 Thanks, Susu -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Video-played-using-vlc-media-player-from-a-windows-media-server-in-not-getting-stored-in-cache-tp4662172p4662176.html Sent from the Squid - Users mailing list archive at Nabble.com.
