Hi, I am able to compile and get squid running on my ubuntu machine. However, when I see my proxy setting in my firefox: Manual proxy configuration: HTTP Proxy: 127.0.0.1 Port: 3128 And when when I load 'www.google.com' in my firefox , I get this error page: The proxy server is refusing connections Firefox is configured to use a proxy server that is refusing connections. * Check the proxy settings to make sure that they are correct. * Contact your network administrator to make sure the proxy server is working. And when I load '127.0.0.1/plain.txt' in my firefox, I get this error message: ERROR The requested URL could not be retrieved While trying to retrieve the URL: http://127.0.0.1/plain.txt The following error was encountered: * Access Denied. Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect. Your cache administrator is webmaster. Can you please tell me what am I missing in setting up my squid as the http server? Thank you.
