Note that I worked with Folkert Van Heusden to get some options added to his httping program to allow "ping" style testing against any HTTP server out there using HTTP/TCP.

See:

I find it slightly ironic that people are now concerned about ICMP ping no longer returning queuing information given that when I started working on bufferbloat, a number of people claimed that ICMP Ping could not be relied upon to report reliable information, as it may be prioritized differently by routers. This "urban legend" may or may not be true; I never observed it in my explorations.

In any case, you all may find it useful, and my thanks to Folkert for a very useful tool.
