CRLF's are only required for the headers themselves (including the blank line separating header and data). The data can be just \n-delimited. system() should work fine, but you might want to check its returnvalue and also check your webserver's error log (usually stderr is piped to a log, not to the browser). -- Dan Nelson dnelson@allantgroup.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
