issue with an irule for validating host header and irule to insert the source IP address

Hi Thiyagu,

Can you try merging iRules?

when HTTP_REQUEST {
	if { [class match [HTTP::header Referer] contains HTTP_REFERER_ALLOW_LIST] } {
		HTTP::header insert "srcaddr" [IP::remote_addr]
	}
	else {
		HTTP::respond 400 content "Bad Request" Content-Type "text/html"
	}
}
