error occurs, a server (does not have to be a Web server) 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 http://pcsupport.about.com/od/findbyerrormessage/a/502error.htm 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 of the time the error is thrown, the upstream server is functioning appropriately. The proxy or gateway and upstream http://www.tech-faq.com/502-proxy-error.html 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 response (502 Proxy Error).
