The problem
A form may appear to send successfully and then repeat or show a confusing message after refresh.
Recommended approach
Use a POST-redirect-GET flow, server-side validation and a one-time request token where appropriate.
Step-by-step checklist
- Validate fields server-side.
- Process the POST once.
- Store a success/error result in session or redirect state.
- Redirect to a clean result URL.
- Prevent duplicate submissions with a request token when needed.
