I noticed that lb_selected event may not occur for each http_request event.
Can you clarify what lb_selected event does?
Thanks.

LB_SELECTED (Click here) is triggered whenever a load balancing decision has been made. What are you testing with your iRule? Can you provide a sample of what you're testing and debug logs showing what you're seeing that you're not expecting?

For each request. I had an old setup and browser session established that caused me some confusing results initially, so chances are good you've got something similar going on.

Thanks for helping.
I was verifying on the default cookie persistence profile of my virtual server.
I have a virtual server with 2 members in the pool.
I attached a irule with the virtual server.
My irule is as follows:
when HTTP_REQUEST {
if { [HTTP::cookie exists "USER_ID"] } then {
if { [HTTP::cookie exists "BIGipServerMy_Pool"] } then {
log local0. "[IP::client_addr] \t Not Yet Available \t [HTTP::cookie "USER_ID"] \t [HTTP::cookie "BIGipServerMy_Pool"] \t [HTTP::uri]"
} else {
log local0. "[IP::client_addr] \t Not Yet Available \t [HTTP::cookie "USER_ID"] \t\t [HTTP::uri]"
}
} else {
log local0. "[IP::client_addr] \t Not Yet Available \t\t\t [HTTP::uri]"
}
}
when LB_SELECTED {
if { [HTTP::cookie exists "USER_ID"] } then {
if { [HTTP::cookie exists "BIGipServerMy_Pool"] } then {
log local0. "[IP::client_addr] \t [LB::server addr] \t [HTTP::cookie "USER_ID"] \t [HTTP::cookie "BIGipServerMy_Pool"] \t [HTTP::uri]"
} else {
log local0. "[IP::client_addr] \t [LB::server addr] \t [HTTP::cookie "USER_ID"] \t\t [HTTP::uri]"
}
} else {
log local0. "[IP::client_addr] \t [LB::server addr] \t\t\t [HTTP::uri]"
}
}
when LB_FAILED {
if { [HTTP::cookie exists "USER_ID"] } then {
if { [HTTP::cookie exists "BIGipServerMy_Pool"] } then {
log local0. "[IP::client_addr] \t [LB::server addr] \t [HTTP::cookie "USER_ID"] \t [HTTP::cookie "BIGipServerMy_Pool"] \t [HTTP::uri]"
} else {
log local0. "[IP::client_addr] \t [LB::server addr] \t [HTTP::cookie "USER_ID"] \t\t [HTTP::uri]"
}
} else {
log local0. "[IP::client_addr] \t [LB::server addr] \t\t\t [HTTP::uri]"

Does it mean that when LB is selected in the first request, the next request by the same client will not require LB_SELECTED event?
Thanks.

Can you elaborate on the old setup and browser session established which resulted in some confusing result?
How did you detect or prevent such setup?
Thanks.

NimbostratusI got same problem. LB_SELECTED event not fired everytime, so made wrong flow in my persistence uie irule, don't know how to force it fire everytime
