Is HTTP::header available for LB_SELECTED, LB_FAILED & PERSIST_DOWN

Can you please let me know if HTTP::header commands are available for the following events. Want to use [HTTP::header exists <header_name>] for these events. LB_SELECTED LB_FAILED PERSIST_DOWN

Hi Maria,

I tested events... working.

when LB_SELECTED {
	if { [HTTP::header exists "Host"] } {
	    log local0. "LB_SELECTED Host: [HTTP::header host]"
	}
}
 
when LB_FAILED {
	if { [HTTP::header exists "Host"] } {
	    log local0. "LB_FAILED Host: [HTTP::header host]"
	}
}
 
when PERSIST_DOWN {
	if { [HTTP::header exists "Host"] } {
	    log local0. "PERSIST_DOWN Host: [HTTP::header host]"
	}
}
