Perhaps, I'm wrong, but I get the distinct impression that all
the "software" at www.eeye.com does is look at the version of apache
that is returned for an HTTP connect (probably just a HEAD).

It does check or else I wouldn't have gotten the "not vulnerable" message on
my 1.3, which is less than .26 after patching it or, much less, seen such a
positive response on SANS list. I have been able to verify that 100% of the
"attempts" using the eEye.com software have actually been picked up and
logged. If there was no attempt to see if it was vulnerable via exploit then
the attempt would not be logged.
