HTTP 411 Length Required Errors

[swheat]

Greetings, we'd like to use nginx to balance for multiple instances of
core grid services for the Atlanta Clinical & Translational Science
Biomedical Informatics Grid.  We've used nginx successfully on several
other projects, but this time we're seeing the errors below when
accessing from grid clients.  Note that these registration requests
succeed when pointed directly to the JBoss container hosting the
back-end grid services but not when pointed to nginx.  These clients are
based on caGrid (cancer research grid) and Globus grid foundation.  This
is the first time we've used nginx in conjunction with these types of
clients, so we suspect it has something to do with these clients, but we
noticed this previous nginx thread  and wondered if others have had and
solved this problem recently either with nginx configuration or by
modifying client behavior.  Any help or suggestions would be greatly
appreciated...thanks!
