title: Differences of pragma: no-cache and Cache-Control: no-cache
body: <p>I have two identical instances of the Java EE Application deployed in two different servers. However, in server A (HTTP, pragma: no-cache), page refreshes fine while in server B (HTTPS, Cache-Control: no-cache), page refreshes with old data retained. I'm curious about the difference since it's the only obvious difference in the headers sent.</p>
