Dear all, My browser works if I give him the proxy address with port 80 or 3128 but doesn't work via default gateway. I gave the following command on the command prompt of windows and got the following output. C:\> telnet 192.168.0.29 80 HTTP/1.0 400 Bad Request Server: squid/2.5.STABLE5 Mime-Version: 1.0 Date: Fri, 24 Feb 2006 12:05:34 GMT Content-Type: text/html Content-Length: 1219 Expires: Fri, 24 Feb 2006 12:05:34 GMT X-Squid-Error: ERR_INVALID_REQ 0 X-Cache: MISS from proxy Proxy-Connection: close <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.or g/TR/html4/loose.dtd"> <HTML><HEAD><META HTTP-EQUIV="Content-Type" CONTENT="text/ html; charset=iso-8859-1"> <TITLE>ERROR: The requested URL could not be retrieved </TITLE> <STYLE type="text/css"><!--BODY{background-color:#ffffff;font-family:ver dana,sans-serif}PRE{font-family:sans-serif}--></STYLE> </HEAD><BODY> <H1>ERROR</H1 > <H2>The requested URL could not be retrieved</H2> <HR noshade size="1px"> <P> Whil e trying to process the request: <PRE> www.yahoo.com &# 3;&# 3;&# 3; </PRE> <P> The following error was encountered: <UL> <LI> <STRONG> I nvalid Request </STRONG> </UL> <P> Some aspect of the HTTP Request is invalid.
