Yes, I already implemented my callback based on request, response and handle()
provides both as parameters.
I am also playing around with cache directives etc.. and debugging
conditionHandle to get the behaviour I want.
public class StrongEtagCallback implements Uniform {
private static Logger log =
Logger.getLogger(StrongEtagCallback.class.getName());
private static List<CacheDirective> cacheDirectives = new
ArrayList<CacheDirective>();
private DomainResource d;
public StrongEtagCallback(DomainResource domainResource) {
d = domainResource;
cacheDirectives.add(CacheDirective.mustRevalidate());
}
@Override
public void handle(Request request, Response response) {
String eTag = ETagFactory.getEtag(d);
if (eTag != null) {
log.log(Level.FINEST, "sending ETag <" + eTag + "> for
" + d);
response.getEntity().setTag(new Tag(eTag, false));
response.getEntity().setModificationDate(d.getLastModified());
response.setCacheDirectives(cacheDirectives);
}
}
}
