title: Java web start: download only the first time?
body: <p>We have an application running with java web start. It works great, and it is launched with an HTML link to JNLP.</p>
  
  <p>However, we need to launch this app several times a day. Is there a way to not download it every single time we want to launch it ? I though that would be put in cache in order to download it only the first time or after updates.</p>
