Measures HTTP roundtrip times (web servers and caches) for SmokePing.

notes => <<DOC,
You should consider setting a lower value for the C<pings> variable than the
default 20, as repetitive URL fetching may be quite heavy on the server.
The I<fill>, I<size> and I<udp> EchoPing variables are not valid for EchoPingHttp.
