NimbostratusPrevious iRules on 9.1.2 stop working on 9.2.2
We have following iRules working on BIG-IP 9.1.2:
iRules attached to TCP Virtual Server A:
when CLIENT_ACCEPTED {
TCP::collect
}
when CLIENT_DATA {
...
Set key and data according to TCP packet payload
set key2 [list $key any]
session add uie $key2 $data
...
TCP::release
TCP::collect
}
iRules attached to TCP Virtual Server B:
when SERVER_CONNECTED {
TCP::collect
}
when SERVER_DATA {
...
Set key according to TCP packet payload
set key2 [list $key any]
set data [session lookup uie $key2]
...
TCP::release
TCP::collect
}
The iRules are simple: store data into session table when VIP A receives TCP packet, and retrieves previously stored data when VIP B returns TCP response.
This is working perfectly find on BIG-IP 9.1.2. Now we have updated the BIG-IP to 9.2.2 and the iRules are not working: previous stored data cannot be retrieved in the second iRules script.
Is there any changes in iRules command "session"? Any help is appreciated!
Otherwise we have to switch back to BIG-IP 9.1.2. Thanks again!
