Hi Jim,
You can write a Jersey-based filter using the latest 0.9 snapshot. See
this email thread for writing Jersey filters:
http://markmail.org/search/?q=list%3Anet.java.dev.jersey.users+filter#query:list%3Anet.java.dev.jersey.users%20filter+page:1+mid:p7yxygz4wpakqno5+state:results
A similar type of filter could also be written for the client side API
(for testing and other purposes).
Would the filter you plan to write be a generic filter with no
application dependencies? if so would you be open to contributing such a
filter back to the Jersey project?
Paul.
