They did not execute the head(1) command that you would execute if you
typed 'head /etc/motd' on your shell prompt; they made an HTTP HEAD
request, the point of which is to get the headers you would get on a GET
request, without the page itself - this is handy for browsers that want
to check if a particular page has changed.

But yes, as discussed in the thread, the goal was probably to check
your Apache's version.

G'luck,
