4×× Client Error
407 Proxy Authentication Required
Similar to 401 Unauthorized, but it indicates that the client needs to authenticate itself in order to use a proxy.
The proxy MUST send a Proxy-Authenticate header field1 containing a challenge applicable to that proxy for the target resource. The client MAY repeat the request with a new or replaced Proxy-Authorization header field2.
