Jan Engehausen commented on CXF-5508:
-------------------------------------
Hi Sergey,
okay I still think there's an issue here: We're using
http://docs.oracle.com/javaee/6/api/javax/ws/rs/core/Request.html#evaluatePreconditions%28java.util.Date,%20javax.ws.rs.core.EntityTag%29
and pass in a weak ETag value (with {{If-None-Match}} header) and the last
modified timestamp (with {{If-Modified-Since}} header) - the values are
obtained from a previous request. Neither ETag value nor timestamp have
changed. In my opinion the preconditions are *not* met; ETag values match, but
we say "send request if ETag does not match or resource has been modified", in
this case a non-{{null}} value should be returned by
{{evaluatePreconditions(Date, EntityTag)}} - currently {{null}} is returned,
making us send a completely fresh response instead of status code 304.
What do you think?
Kind regards,
Jan
