Excuse me. This will undoubtedly show my ignorance, but.
What would that serve? If they are tying up your lines to prevent
your serving others, what advantage would holding the line open for
them serve? Unless the bottleneck is processor time or file access
time and not the network connection. What about honoring their
requests with a much smaller file? How about one which is truncated
in such a way that whatever would be recognized as the EOF doesn't
exist, then closing the connection from the server side? Packages 1
of 16 received, door closed without notice. Would this perhaps hang
the spider? By giving it only a fraction of what it expects and just
not sending the rest?
Just some uninformed opinions from someone who only BRIEFLY browsed
through a laymans explanation of various DOS hacks in a OS specific
magazine.
