AltocumulusPersitence via Xfor
Hello, I have a problem with the balancing of some systems. In the diagram below you can see the current balancer configuration.
Internet --> FrontEndF5 --> SecureProxy --> BackEndF5 --> Ohs-Pool --> BackEndF5 --> PortalServer-Pool
What I would like to achieve is to be able to balance the servers in the Ohs-Pool and the servers in the PortalServer-Pool using the Xfor field. From the logs I can see that the HTTP::header field "X-Forwarded-For is valid, but the iRule I created seems not to work and I get an error from the web portal.
My iRule:
when HTTP_RESPONSE {
if { [HTTP::header "X-Forwarded-For"] } {
persist add uie [HTTP::header "X-Forwarded-For"]
}
}
when HTTP_REQUEST {
if { [HTTP::header "X-Forwarded-For"] } {
persist uie [HTTP::header "X-Forwarded-For"]
}
}
Hello,
You seem to be using the article https://support.f5.com/csp/article/K7392 but you have not added the "exists" keyword. Also take a look at https://community.f5.com/t5/technical-forum/enable-source-ip-persistence-based-on-x-forwarded-ip-info/td-p/98748 as many people had the same idea.
I will also suggest if you still see issues to try adding One Connect profile under the VIP as described in https://support.f5.com/csp/article/K7964 and also test CARP persistance if needed https://support.f5.com/csp/article/K11362 .
