The ETag header is causing an issue with browser cache not being updated when the server has been updated. Actually a weak ETag, see http://en.wikipedia.org/wiki/HTTP_ETag
Seems like tomcat’s DefaultServlet will only serve weak ETag’s even though tomcat7+ does have code for strong ETag but is never used and there is no documentation on how to set it
A possible solution is to remove If-None-Match request header and ETag response header in apache http server
RequestHeader unset If-None-Match
Header unset ETag

What's the recommended workflow engine in OFBiz? Is it Shark?
OFBiz gave up on Workflow Engines. Shark was implemented last but never really used in OFBiz. Instead of using a Workflow Engine, OFBiz uses an Event Driven Architecture (EDA), so ECAs (SECA, EECA, MECA) are used in OFBiz to drive the Workflow. ECA is the acronym of Event Condition Action. SECAs are for Services (triggered on services conditions), EECAs are for Entity (triggered on entities conditions), MECAs are for Mail.
