Setting Jersey to allow caching?
I have the following returned from a Jersey @GET method. It works, fine but always includes the No-cache header. I'd like to allow the client to cache this data since it rarely changes.
ResponseBuilder rb = Response.ok(c);
CacheControl cc = new CacheControl();
cc.setMaxAge(60);
cc.setNoCache(false);
return rb.cacheControl(cc).build();
The response is always:
Server Apache-Coyote/1.1
Pragma No-cache
Cache-Control no-cache, no-transform, max-age=60

That am I doing wrong here?
This was caused by having BASIC auth turned on.
Specifying this in the context will correct the issue:
<Valve className="org.apache.catalina.authenticator.BasicAuthenticator"
disableProxyCaching="false" />
Hope this helps someone else out.
Your code looks okay.
Which container are you using? Make sure cache is not disabled on it. Also verify downstream response handlers or filters aren't setting the no-cache directive.
