I looked for such a message and the only thing I can find is as follows: 1) _SERVER['HTTP_ACCEPT'] and _ENV['HTTP_ACCEPT'] and change to "*/*", but I don't know if that is the case for all browsers, do you know? 2) _SERVER['REDIRECT_UNIQUE_ID'] and _ENV['REDIRECT_UNIQUE_ID'], _SERVER['REMOTE_PORT'] and _ENV['REMOTE_PORT'], _SERVER['UNIQUE_ID'] and _ENV['UNIQUE_ID'] change, but I don't think the values are predictable, especially between browsers. Do you know of a specific message to look for and is that message the same for all browsers? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
