# HTTP 303 — See Other

**HTTP 303: See Other**

The request succeeded; now go and GET a different URL to see the result.

## What 303 actually means

Designed for the aftermath of a form submission. The POST was handled, and rather than returning a page directly — which leaves the browser able to resubmit on refresh — the server redirects to a result page that the browser fetches with GET. This is the Post/Redirect/Get pattern, and it is why "confirm form resubmission" prompts have largely disappeared from well-built sites.

## Common causes

- A form POST completed and the server redirected to a confirmation page
- An API used Post/Redirect/Get to avoid duplicate submissions
- A long-running job redirected to its status page

## If you're just trying to view the page

1. Nothing — your submission went through and you are being shown the result
2. This is the pattern that stops a page refresh from re-charging your card, so seeing it is good news

## If it's your site

1. Use 303 rather than 302 after a POST; it is the code that actually means "change the method to GET"
2. The target should be a plain, safe, refreshable page
3. Not understood by HTTP/1.0 clients, which is irrelevant in practice today
