HTTP 506 Variant Also Negotiates is a server error-class status code defined in RFC2295. The server has a circular content-negotiation configuration error.
Server-error responses admit the fault is on the server's side: the request was valid, but the server failed to fulfil it. On the wire, the response begins with the status line HTTP/1.1 506 Variant Also Negotiates.
