It is suitable for implementing components such as revers
a proxy server. The problem is typically caused for one of two reasons: 1 – The Internet Security and Acceleration (ISA) is configured to throw a

proxy error to help guard against external or internally-based Internet threats, and 2- http response example The client or server computers are misconfigured or using outdated software. What is a 502 Proxy Error? A 502 proxy http status codes cheat sheet error is typically thrown in the HTTP cycle. When the error occurs, a server (does not have to be a Web server) is filling a role similar to a proxy or a gateway server. https://github.com/nodejitsu/node-http-proxy When a client computer sends an HTTP request (typically a web browser, but can be any software application that is capable of making an HTTP request), it will pass through the server in order to obtain access to the desired URL. The proxy or gateway subsequently receives a 502 error, or invalid response, from the server located “upstream” in the attempt to fulfill the client request. The majority http://www.tech-faq.com/502-proxy-error.html of the time the error is thrown, the upstream server is functioning appropriately. The proxy or gateway and upstream servers just cannot agree on the appropriate protocol for exchanging the information requested in the original client HTTP request. In many of these cases, either the proxy or upstream server are not configured correctly or are running incompatible software. Why Does a 502 Proxy Error Get Thrown? During a typical web browsing session, the following is an example of the classic HTTP cycle when a client computer and web server are communicating: Client Computer: The IP address of the desired website will be obtained from the URL of the site from the DNS server. Client Computer: The computer obtains an IP socket connection to the desired IP address and then sends an HTTP data stream through the IP address. Web Server: HTTP data is sent back to the client computer in response to the original HTTP request. The HTTP response will include status codes and other useful information for the client computer. Client Computer: If there is an error in the client’s request or server’s ability to respond, there will be an HTTP error code of 502 included in the server’s respon
response. 10.1 Informational 1xx 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. There are no required headers for this class of status code. Since https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy http code and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not http proxy error yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status code indicates that the client's request was successfully received, understood, and accepted. 10.2.1 200 OK The request has succeeded. The information returned with the response is dependent on the method used in the request, for example: GET an entity corresponding to the requested resource is sent in the response; HEAD the entity-header fields corresponding to the re
