I've installed squid 2.6STABLE13 and its popping up this error in the web browser unless the browser is specifically set up to use the proxy: ERROR The requested URL could not be retrieved While trying to process the request: GET / HTTP/1.1 Host: www.google.com.au User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.4) Gecko/20061201 Firefox/2.0.0.4 (Ubuntu-feisty) Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: PREF=ID=7aa0efd17af3c427:TM=1180072030:LM=1180072030:S=j62Hn0QgEm84t2x7 Pragma: no-cache Cache-Control: no-cache The following error was encountered: * Invalid Request Some aspect of the HTTP Request is invalid. Possible problems: * Missing or unknown request method * Missing URL * Missing HTTP Identifier (HTTP/1.0) * Request is too large * Content-Length missing for POST or PUT requests * Illegal character in hostname; underscores are not allowed I've put in http_port 80 transparent in squid.conf, as far as I'm aware that is all that's needed for it to work in transparent mode now?
