[Helma-user] Obscure Error Messages in helma.server.log

[Hannes Wallnoefer]

Hi Tobi,

from what you say it may well have been a DOS attack, but the log
entries do not really give a clear indication.

The Illegal cookie thing obviously tries to use a tomcat ajp13
connector exploit:
http://issues.apache.org/bugzilla/show_bug.cgi?id=10383
I think the fact that jetty logs an error message tells us that it's
not vulnerable.

The second thing is an error that helma currently throws when there
are two cookies with the same name. This isn't that uncommon as
cookies can come with different domains and path names, so I should
look into this, i.e. it's actually a helma bug that the user gets an
error page.

Finally, the EOFException in writeResponse() just tells us that the
client has closed the connection while we were still writing to it,
i.e. not a big issue at all.
