Java – invalid Jersey expires header

I am using Jersey bundle 1.11 to provide some restful web services

Every time I use chrome to browse rest resources, I will notice that HTTP header expires is set to Thu, 01 Jan 1970 01:00:00 CET

I tried to edit the response and add:

return Response.ok( myObject ).expires(new Date(System.currentTimeMillis() + 3000)).build();

Unfortunately, this adds another HTTP header expires instead of replacing the old one

What's the problem?

Solution

Fwiw, I see exactly the same behavior The container here is JBoss 4.2 3. This is a put method using basic authentication My answer is as follows:

Date exp = new Date(System.currentTimeMillis() + lifetime);
return Response.noContent().expires(exp).build();

When called with curl, these are the returned headers:

< HTTP/1.1 204 No Content
< Server: Apache-Coyote/1.1
< Pragma: No-cache
< Cache-Control: no-cache
< Expires: Thu,01 Jan 1970 01:00:00 CET
< X-Powered-By: Servlet 2.4; JBoss-4.2.3.GA (...
< Expires: Tue,13 Mar 2012 11:08:54 GMT
< Date: Tue,13 Mar 2012 11:08:24 GMT
