      Description

      zkLoader outputs html which references zk.wcs, zk.wpd and zul.lang.wpd. These are given header to encourage them to cache:

      HTTP/1.1 200 OK
      Cache-Control: public, max-age=31536000
      Content-Encoding: gzip
      Content-Language: en-US
      Content-Type: text/javascript;charset=UTF-8
      Expires: Sun, 09 Dec 2012 19:14:22 GMT
      Last-Modified: Sat, 10 Dec 2011 19:04:32 GMT
      Server: Jetty(7.x.y-SNAPSHOT)
      Content-Length: 98783
      Connection: keep-alive

      Yet when I hit the page repeatedly with either Google Chrome or Firefox the developer consoles show that the browser is refetching the data. This is adding up to 0.6 seconds of page load time due to the size of those resources.

      Test Page: http://glowing-light-1070.herokuapp.com/zktodo_d.zul
      Test page source code: https://github.com/simbo1905/ZkToDo2/blob/master/src/main/webapp/zktodo_d.zul

      [Heroku cloud swaps out the app if it is idle; please wait many seconds first load].

      I get the same behavior running on a local jetty server (mvn jetty:run).
