Hi, I think I found something in the cache.log I posted before. sendRequest: HTTP Server conn* local=PUB_IPv4_ADDR_3 ... sendRequest: HTTP Server conn* local=PUB_IPv4_ADDR_2 It seems that Squid sometimes connects to the remote HTTP server with either one of the available addresses on the Squid box (eg. PUB_IPv4_ADDR_2, PUB_IPv4_ADDR_3, etc). These addresses are on ppp interfaces. In fact, I noticed that if the Firefox client shows this error message in its console as in my previous post: The connection to wss://ed1lncb62801.webex.com/direct?type=websocket&dtype=binary&rand=1602830016480&uuidtag=5659FGE6-DF29-47A7-859A-G4D5FDC937A2&gatewayip=PUB_IPv4_ADDR_2 was interrupted while the page was loading. then I see a corresponding 'sendRequest: HTTP Server conn* local=PUB_IPv4_ADDR_3' when trying to connect to the same origin. So I'm deducing that the remote websocket server is expecting a client connection from PUB_IPv4_ADDR_2 when in fact Squid is trying to connect from PUB_IPv4_ADDR_3 -- hence the "interruption" message. My test Squid instance is running on a multi-ISP router, so I guess I have to figure out how to either force connections out one interface only for the Squid cache or tell Squid to only bind to one interface. It's only a wild guess though. Vieri _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
