As far as I understand the "resubmit problem" is just sign of poor implementation that violates SHOULD NOT in the HTTP RFC:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.13

This problem can be elegantly solved within existing standards: Opera simply goes back in history without resubmitting forms, and resubmits only when user clicks standard Reload button (or F5, etc.)
