Yes, this is how Squid works, even if Squid is tunneling at TCP level. After Squid notices that the server has closed the Squid-server connection, Squid closes its end of that connection as well, regardless of what the client is doing (in some cases, there may be no client at all at that point). Some may argue that the lack of accurate closure timing propagation for TCP tunnels is a Squid bug or a missing Squid feature, but that argument does not change the answer to your question about the current Squid behavior. > 2. Does proxy server have option to stop item 1? No. If you want to discuss whether adding such an option is a good idea please detail your use case (i.e. _why_ such an option is needed). HTH, Alex. P.S. Please note that Squid works above the individual TCP packet layer. Squid operates on TCP sockets and does not see or send individual TCP packets. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
