Hello There -- Would like to get your assistance on logging from an iRule. I would like the irule to log to the LTM logs to see if the connection is sending over the cookie parameter's value      ...

Hi viziony,

check out the modified iRule below...

 


when HTTP_REQUEST {
	if { [HTTP::header value "Route-to-AB"] equals "YES" } then {
		pool pool-A
		log local0.info "Header \"Route-to-AB\" value is \"YES\"."
	} else {
		pool pool-B
		log local0.info "Header \"Route-to-AB\" value is \"[HTTP::header value "Route-to-AB"]\"."
	}
}

 

Note: You may change the log-level "info" to "debug" if subsequent messages getting supressed. LTM has a filter for non debug messages.

Cheers, Kai
