Official Explanation
This code is similar to 401 (Unauthorized), but indicates that the client must first authenticate itself with the proxy. The proxy MUST return a Proxy-Authenticate header field (Section 14.33) containing a challenge applicable to the proxy for the requested resource. The client MAY repeat the request with a suitable Proxy-Authorization header field (Section 14.34). HTTP access authentication is explained in "HTTP Authentication: Basic and Digest Access Authentication" [RFC2617].
"407 Proxy Authentication Required" is supported by most Web Servers.
