Back/Forward Buttons
The browser's Back, Forward, and Refresh buttons can have unexpected results when working in a web app. The Back and Forward buttons re-display cached copies of the requested posts, but this might be stale information. The Refresh button guarantees that the information is not stale, but if the last action was a database submission, the information will be re-submitted, and this isn't generally what you want to do. (Sometimes the Back and Forward buttons can do this also, if the page in question contained an expiration date that has passed.)
To avoid these issues, QDL provides its own Back, Forward and Refresh buttons as part of the default layout. Clicking these buttons will request a fresh copy of the previous, current, or next page, but without re-submitting any information.
