408 Request Timeout

If a client is too slow to send a full HTTP request, a server can send back a 408 Request Timeout error response.

A request coming in too slow can happen for a variety of reasons, including slow internet connections, completely lost internet connections or bad actors.

When a server sends back the 408, it no longer wants to wait for the request and kills the connection.

A robust client might try to repeat the request as soon as they receive this response.

Example

HTTP/1.1 408 Request Timeout
Connection: close
Content-Type: text/plain

Too slow! Try again
