Hi I am using Squid redhat as a proxy server but when we go to hotmail.com and others webmail login we get this error message. ERROR The requested URL could not be retrieved ---------------------- While trying to retrieve the URL: /cgi-bin/hmhome?fti=yes&curmbox=00000000%2d0000%2d0000%2d0000%2d000000000001&a=f3ddbed0af0ad5aeb6788d7f105d67cbc4851255bb4b1dee3cff47a09359f3ec The following error was encountered: Invalid URL Some aspect of the requested URL is incorrect. Possible problems: Missing or incorrect access protocol (should be `http://'' or similar) Missing hostname Illegal double-escape in the URL-Path Illegal character in hostname; underscores are not allowed Your cache administrator is root. How can I fix it?, I can edit the squid.conf file but not sure how to fix this. Thanks
