is filling a role similar to a proxy or a gateway server. 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, 502 proxy error chrome or invalid response, from the server located “upstream” in the attempt to fulfill the client request. The majority 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.

HTTP provides an orderly way for your Web browser to communicate with Web servers -- http://www.tech-faq.com/502-proxy-error.html the machine chatter that goes on behind the scenes of your Internet experience. As a part of HTTP, whenever your browser interacts with a server, such as when you attempt to load a Web page, the server responds with an Internet status code telling the browser how the interaction went.

Code 404 is the best-known HTTP error code, indicating that the server couldn't find what your browser was looking for, but code 502 also shows up from time to time.Code 502: Bad GatewayHTTP error code 502 indicates a "bad gateway" or "bad proxy." When you visit a website, your browser doesn't necessarily communicate directly with the server that hosts the site.
