The HTTP 303 See Other redirect status response code, usually sent back as a result of a PUT or POST operation, indicates that the redirects don't link to the newly uploaded resources but to another page, like a confirmation page or an upload progress page. The method used to display this redirected page is always GET.

Why does MDN look different?
MDN is changing to focus just on documenting web technologies. All the same great content is still here; we’re just changing some visual elements and navigation, to help you more quickly find the web technology docs you’re looking for.
But don’t worry, MDN and Mozilla are still together! In fact, we're updating MDN’s look to reflect Mozilla's new logo and colors.
