Hi Mark,
Did you happen to come up with a solution for this problem? I've been
encountering a similar problem with the university's Google search appliance
crawler bombarding DSpace with nonsensical URL queries like these:
[http://helda.helsinki.fi]/D/data/Eduskunnan
[http://helda.helsinki.fi]/dstudhope/My%20Documents/Research/Presentations/2004-2006/CRM%20SIG%2006/EAT-Draft%20scope%20notesv6.doc
[http://helda.helsinki.fi]/y/kon/He/LVK
[http://helda.helsinki.fi]/T/UlXAoitari/PERIMlSTOJM
The apache logs show the response codes for these queries to be 200 OK,
while the Jetty app server (connected via mod_proxy) throws a 500 server
error (I'll paste an example to the end of the message).
