Setting Jersey to allow caching?

Question

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
 Expires    Wed, 31 Dec 1969 19:00:00 EST
 Content-Type   application/xml
 Content-Length 291
 Date   Tue, 16 Feb 2010 01:54:02 GMT

That am I doing wrong here?

Answer 1

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.

Answer 2

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.
