HTTP_REQUEST_SEND
       Triggered immediately before an HTTP request is sent to the server-side TCP stack.

DESCRIPTION
       An iRule event triggered immediately before an HTTP request is sent to the server-side TCP stack. This is a
       server-side event. Because of that, if you wish to execute commands in a client-side context in this event,
       you will need to use the clientside command to do so.

Examples
	##
	when HTTP_REQUEST_SEND {
	  TCP::collect 12
	}

	## Replace HTTP host header value with the connected server IP and port
	when HTTP_REQUEST_SEND {

	   # Need to force the host header replacement and HTTP:: commands into the clientside context
	   # as the HTTP_REQUEST_SEND event is in the serverside context
	   clientside {
	      # Replace the HTTP host header with the connected server IP and port
	      HTTP::header replace Host "[IP::server_addr]:[TCP::server_port]"
	   }
	}
