Hello haproxy geeks, I am trying to use haproxy in the following scenario that persistent tcp connections using source ip.
The client establishes a tcp connection (such as ssh for e.g),to vip, and vip allocates a real server rs1. I can see the stick table entry via cli. When this tcp session keeps a long time, during this period, the relevant stick table entry's expiration time is always decresing, until it is removed for timeout. But at this time point the existing tcp connection is still alive. If I close the connection, and start a new one, it is allocated a different real server, for round robin and no stick table entry matches. My question is "is it normal that timeout the stick entry even there is still a session alive from that client?" if yes, why it is designed such a way. Is it more comprehensible that the stick table starts timing out after no session from that client. if no, is there any configuration in haproxy I missed to avoid the stick table timeout in case there still existing live session from that client. Thanks a lot for your help and information. Alex.
