TWiki has had a problem with losing edits when the browser back button is pressed. IIUC, it is related to the HTML head and caching.

Here are two relevant pages from Codev:

• Codev.RefreshEditPageDiscuss
• Codev.BackFromPreviewStillLosesText

Do a Google search for [back from preview] on twiki.org to find additional relevant pages.

This page on Wikipedia may be helpful when I strive to learn more: http://meta.wikipedia.org/wiki/Cache_strategy
