This is actually a feature of the web browser that is saving you from having duplicate information. Form submissions are usually task processing in nature, which means for instance that if someone hits 'back' from your order confirmation page if the web browser resubmitted your form in all likelyhood it would generate a new order (now duplicate) and take you to the confirmed order page for the new order.

This doesn't really have anything to do with the fact that it is a secure site. If you redirect at the end of every form handler, you will not have this problem. This does however make report filtering type forms a bit more difficult, but that situation would be one of the few where a method="get" form would be an appropriate choice.
