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 http://www.tech-faq.com/502-proxy-error.html external or internally-based Internet threats, and 2- The client or server computers are misconfigured or using outdated software. What is a 502 Proxy Error? A 502 proxy error is typically thrown in the HTTP cycle. When the error http://stackoverflow.com/questions/6660360/error-code-502-proxy-error-the-isa-server-denied-the-specified-uniform-resourc 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 can 502 error 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 servers 502 proxy error 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). How to Fix 502 Proxy Errors (Client Side) One of the most frustrating things for the average computer user is determining where the problem resides when receiving the 502 Proxy Error.

Thanks. apache http proxy share|improve this question asked Jul 12 '11 at 6:36 chAmi 74431122 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted The problem is that you're routing your localhost traffic through your upstream gateway proxy. The upstream gateway proxy refuses to send the traffic back, either because "localhost" has a different meaning to it, or because it's trying to prevent a security threat called "proxy bounceback." What URL are you using to access your site? Put that URL's hostname in your proxy exemption list. share|improve this answer answered Jul 12 '11 at 13:20 EricLaw 42.9k492137 That's might the reason i checked my proxy setting "Bypass proxy settings for local address" in the browser settings and it works for me.
