exchanging data. Given that Internet protocols are quite clear, it often means that one or both machines have been incorrectly or incompletely programmed. Fixing 502 errors - general This problem http://forums.isaserver.org/502_Proxy_Error%25_Not_implemented_(-2147467263)/m_2002051336/tm.htm is due to poor IP communication between back-end computers, possibly including the Web server at the site you are trying to visit. Before analysing this problem, you should clear your browser cache completely. If you are surfing the Web and see this problem for all Web sites you try to visit, then either 1) your ISP has a major equipment http://www.checkupdown.com/status/E502.html failure/overload or 2) there is something wrong with your internal Internet connection e.g. your firewall is not functioning correctly. In the first case, only your ISP can help you. In the second case, you need to fix whatever it is that is preventing you reaching the Internet. If you get this problem for only some of the Web sites you try to visit then it is likely to be a problem at those sites i.e. one of their pieces of equipment is failing/overloaded. Contact the people at those sites. Fixing 502 errors - CheckUpDown Our service monitors your site for HTTP errors like 502. Use of proxies and caching is increasing on the Web. Our CheckUpDown robot will always try to "drill through" to the real computer that actually hosts the Web site, but we do not have complete control over where our HTTP request actually ends up. If only one link in the chain of computers dealing with our HTTP request is broken, then an error such as 502 can easily occur. Please contact us (email

It includes codes from IETF internet standards, other http://support.hostgator.com/articles/cpanel/error-page-codes IETF RFCs, other specifications, and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; an HTTP client must recognise these five classes at a minimum. The phrases used are the standard wordings, but any human-readable alternative can be provided. Unless otherwise stated, the 502 proxy status code is part of the HTTP/1.1 standard (RFC 7231).[1] The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.[2] Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information,[3] but not all of those are here (note that these sub-codes only appear in the response payload and in documentation; not in the place of an actual HTTP status code).

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not[note 1] send a 1xx response to an HTTP/1.0 client except under experimental conditions.[4] 100 Continue The server has received the request headers and the client should proceed to send the request body (in the case of a request for which a body needs to be sent; for example, a POST request). Sending a large request body to a server after a request has been rejected for inappropriate headers would be inefficient. To have a server check the request's headers, a client must send Expect: 100-continue as a header in its initial request and receive a 100 Continue status code in response before sending the body. The response 417 Expectation Failed indicates the request should not be continued.[2] 10

All HTTP requests (the type of requests generated by your browser when you attempt to load a page) generate a status code. However, your browser will generally only display a status code associated with an error after an attempted action fails. There are 5 classes of status codes, and the term error codes specifically refers to the two classes of status codes that indicate these errors. This article will cover the following codes: What is a Client Error Code? 400 : Bad Request 401 : Authorization Required 403 : Forbidden 404 : Not Found 405 : Method Not Allowed 406 : Not Acceptable (encoding) 407 : Proxy Authentication Required 408 : Request Timed Out 409 : Conflicting Request 410 : Gone 411 : Content Length Required 412 : Precondition Failed 413 : Request Entity Too Long 414 : Request URI Too Long 415 : Unsupported Media Type 421 : Too Many Connections What is a Server Error Code? 500 : Internal Server Error 501 : Not Implemented 502 : Bad Gateway 503 : Service Unavailable 504 : Gateway Timeout 505 : HTTP Version Not Supported Custom Error Pages What is a Client Error Code?
