Use curl to measure and report HTTP response times (pre-, start- and total transfer)

	#!/bin/bash
	#
	# Report time to first byte for the provided URL using a cache buster to ensure
	# that we're measuring full cold-cache performance

	while (($#)); do
	echo $1
	curl -so /dev/null -H "Pragma: no-cache" -H "Cache-Control: no-cache" \
	-w "%{http_code}\tPre-Transfer: %{time_pretransfer}\tStart Transfer: %{time_starttransfer}\tTotal: %{time_total}\tSize: %{size_download}\n" \
