Sarah, Referer is just one HTTP header - it is separate from response codes (200, 404 etc) and other headers. No error is thrown if it's not present so content is passed on as normal. But because HTTP headers can be changed along the response chain from server to client they can't be relied upon. -- Chris Knowles ******************************************************************* List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: [EMAIL PROTECTED] *******************************************************************
