Sergey Beryozkin commented on CXF-5508:
---------------------------------------
I'm pretty the last change came after I did some TCK work,
So we have
{code:java}
public ResponseBuilder evaluatePreconditions(Date lastModified, EntityTag eTag)
{
final ResponseBuilder rb = evaluatePreconditions(eTag);
if (rb == null) {
// the ETag conditions match; so now conditions for last modified
must match
return evaluatePreconditions(lastModified);
} else {
// the ETag conditions do not match, so last modified should be
ignored
// see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
(section 14.26 for
// "If-None-Match", behaviour not specified for "If-Match", section
14.24)
return null;
}
}
{code}
and the relevant text:
"If none of the entity tags match, then the server MAY perform the requested
method as if the If-None-Match header field did not exist, but MUST also ignore
any If-Modified-Since header field(s) in the request. That is, *if no entity
tags match, then the server MUST NOT return a 304 (Not Modified) response*."
The code above will ignore If-Modified-Since if none of the entity tags match,
i.e, if they match, ResponseBuilder is not null, and the dates are checked, but
of they do not match then null is returned.
Where is the problem ?
