how to create a persistance irule for application

As of now we tried all default persistance, but we are facing issues on this.what is the issue?

 

 

1) On what basis Irule should be configured ?there is example universal persistence irule in askf5 sol. is it somehow helpful?

2) How to analyse packets on F5 to create this irule ?usually i capture end-to-end packet (both client-side and server-side). the following is example tcpdump command i use.

 

 

e.g.

 

tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x or host y.y.y.y and port zzz

 

x.x.x.x is virtual server ip

 

y.y.y.y is pool member ip

 

zzz is service port number

 

 

just in case if you have not yet seen this sol. hope it is helpful to understand how connection is created.
