Hi again,
I just did a test. Connected to the farm, then I can find an entry for
my laptop IP in the file in /proc/net/xt_recent/ :
192.168.161.191....................................jeudi 27 février
2014, 10:44:16 (UTC+0100)
(I used a script found there, if someone is interested:
http://forums.fedoraforum.org/showthread.php?t=224461)
I just closed my browser, and then in around 30s to 1min, my entry is
gone. So apparently when the TCP session is gone, the entry is gone and
the persistence is lost. Is this expected or do I misunderstand something?
I was expecting that the persistence should be kept, regardless of the
current active session, at least as long as the TTL is not over. So here
normally when I close my browser, the TTL should start counting from
3600 to 0 and then only my persistence should be erased.
Thanks

Hi Laura,
Thanks for the information.
I was wondering because we are having issues with a web application
since we switched to a L4 farm. It "seems" some users are switched to
the other backend before the end of the persistence, and therefore
they loose their session and get disconnected from the application. We
are waiting for the provider to help troubleshooting these errors, but
so far when we run with only one backend, we see far less
disconnection error (though there are still a few).
A last question, I've found that the recent information are stored
under /proc/net/xt_recent/ but I wonder if the files (and therefore
the persistence) is cleared when the farm is restarted, or does it
stay? In another way: can I restart a L4 farm without loosing the
persistence?
Thanks

Hi, yes the L4 farm should behave like the TCP farm in that subject.
By other hand, you're absolutely right regarding the TTL field and
the farm is not reloaded automatically. This is a bug and will be
fixed in the next release. Good catch!
Thank you.

Hello,
Can someone please confirm that it works as in TCP Farm with PEN, so
it's the inactivity timeout and not the max session length ? (ie:
3600s
means 1h with no traffic before we remove the persitence)
Also a little feature enhancement, when a L4 farm is started and you
change the persistence time, it says "The sessions TTL for
ZLB-ULG farm
has been modified." but it's NOT applied, it's just written in the
config file.
It would be worth mentionning next to this message that a restart
of the
farm is needed...
Thanks
