We need help with a configuration of mimetype. We do not permit to download determined mimetypes.(e.g. Exe) We do this with allow rules for this mimetypes. (e.g. http,.html,..) We got a problem with a few pages (e.g. www.schueco.de) They use a special content managment. We get a redirection with no content type. The ISA Server denies this connection for the users. --> Redirection looks like this.
