http-ping

http-ping is a small, free, easy-to-use command-line utility that probes a given URL and displays relevant statistics. It is similar to the popular ‘ping’ utility, but works over HTTP/S instead of ICMP, and with a URL instead of a computer name/IP address. Use it to discover if a web site is responding to requests, test the performance of any web site, load-test a web server, or compose scripts that monitor a web site.
