413 Payload Too Large

The 413 Payload Too Large response is used when the client sent a request with a body that’s too big.

Maybe the request was a file upload, and it exceeded the maximum file-size, or maybe it’s an API and it preemptively blocks requests that are unrealisticly large.

It’s a good idea to try and think of reasonable limits for requests, as accepting arbitrary-size HTTP requests could result in denial-of-service attacks.

If this error is temporary, a server can include a Retry-After header to indicate to the client they should just try again after a certain amount of time.

One example of a temporary status could be that the client has an upload-quota and it was exceeded.

If the reason for the error is that the server ran out of disk- space, 507 Insufficient Storage should be used instead.
