HTTP 303 See Other

In short: The result is at another address and should be fetched with GET.

In more detail: Used after a POST to redirect the browser to a result page (Post/Redirect/Get). Reloading the page then does not trigger the action again.

In Depth

When it occurs

• After submitting a form you land on the thank-you page.
• After a purchase you are redirected to the order confirmation.

What you can do

1. As a visitor there is nothing to do, the redirect happens automatically.
2. Developers: set Location to the result page, not to the form address.
