Sergey Beryozkin commented on CXF-2592: --------------------------------------- here is the code for evaluatePreconditions(EntitiTag tag) : public ResponseBuilder evaluatePreconditions(EntityTag eTag) { ResponseBuilder rb = evaluateIfMatch(eTag); if (rb == null) { rb = evaluateIfNonMatch(eTag); } return rb; } evaluateIfNonMatch(EntityTag eTag) should be evaluating If-None-match. Does it not work for you ? If yes then can you please some more details please ? > evaluatePreconditions() in RequestImpl should also check the If-None-Match > header > --------------------------------------------------------------------------------- > > Key: CXF-2592 > URL: https://issues.apache.org/jira/browse/CXF-2592 > Project: CXF > Issue Type: Bug > Components: JAX-RS > Affects Versions: 2.2.5 > Reporter: Kent Tong > > Currently the code is: > public ResponseBuilder evaluatePreconditions(Date lastModified, EntityTag > eTag) { > ResponseBuilder rb = evaluatePreconditions(eTag); > if (rb != null) { > return rb; > } > return evaluatePreconditions(lastModified); > } > public ResponseBuilder evaluatePreconditions(EntityTag eTag) { > String ifMatch = getHeaderValue(HttpHeaders.IF_MATCH); > ... > } > which is checking the If-Match header.
