304
Not Modified

307
Temporary Redirect

The request should be repeated with another URI; however, future requests should still use the original URI.

Permanent Redirect

The request and all future requests should be repeated using another URI.

4xx Client Error

The request contains bad syntax or cannot be fulfilled.

400
Bad Request

The server cannot or will not process the request due to an apparent client error.

401

500
Internal Server Error

A generic error message, given when an unexpected condition was encountered.

501
Not Implemented

502
Bad Gateway

The server was acting as a gateway or proxy and received an invalid response from the upstream server.
