What causes the persistence to be refreshed? I can look at my own connection an see the age time increase with time... when I click some links it doesn't reset, then I click another link and the age resets and goes back to 0.it will be refreshed if bigip receives (processes) request. are you sure if that content is not from (browser or proxy) cache?
if there is persistence to a given node... and that node goes offline, what happens with that persistence record? Is it dropped automatically?i understand the record will be updated upon receiving request.
[root@ve10:Active] config b virtual bar list
virtual bar {
snat automap
pool foo
destination 172.28.19.252:80
ip protocol 6
persist mysource
profiles {
http {}
tcp {}
}
}
[root@ve10:Active] config b pool foo list
pool foo {
monitor all http
members {
200.200.200.101:80 {}
200.200.200.111:80 {}
}
}
[root@ve10:Active] config b profile mysource list
profile persist mysource {
mode source addr
timeout indefinite
}
1. pool members are up, persistence record is created.
[root@ve10:Active] config b pool foo|grep -i pool\ member
+-> POOL MEMBER foo/200.200.200.101:80 active,up
+-> POOL MEMBER foo/200.200.200.111:80 active,up
[root@ve10:Active] config b persist show all
PERSISTENT CONNECTIONS
| Mode source addr Value 172.28.19.251
| virtual 172.28.19.252:80 node 200.200.200.111:80 age 58sec
2. the pool member in persistence record is down but the record still exists.
[root@ve10:Active] config b pool foo|grep -i pool\ member
+-> POOL MEMBER foo/200.200.200.101:80 active,up
+-> POOL MEMBER foo/200.200.200.111:80 inactive,down
[root@ve10:Active] config b persist show all
PERSISTENT CONNECTIONS
| Mode source addr Value 172.28.19.251
| virtual 172.28.19.252:80 node 200.200.200.111:80 age 195sec
3. the client sends another request. persistence record is updated to new pool member.
[root@ve10:Active] config b persist show all
PERSISTENT CONNECTIONS
| Mode source addr Value 172.28.19.251
| virtual 172.28.19.252:80 node 200.200.200.101:80 age 2sec
