Hi I've setup a firewall (Endian Firewall) in small network. This firewall uses squid cache Users must upload csv files in an extranet website. When they upload/submit the csv files, they get: "Zero Sized Reply" - Proxy is set to Transparent - Site doesn't work in Firefox/Chrome (decent browser). It works Only on IE! - Uploading works but one csv file by one. If they upload all toghether, they get "Zero Sized Reply" - Cleaned Cookies and temp files from IE config Any ideas? Thanks
