t3lib/config_default.php (working copy)
'strictFormmail' => TRUE, // Boolean. If set, the internal "formmail" feature in TYPO3 will send mail ONLY to recipients which has been encoded by the system itself. This protects against spammers misusing the formmailer.
'secureFormmail' => TRUE, // Boolean. If set, the internal "formmail" feature in TYPO3 will send mail ONLY to the recipients that are defined in the form CE record. This protects against spammers misusing the formmailer.
'formmailMaxAttachmentSize' => 250000, // Integer. Sets the maximum allowed size (in bytes) of attachments for the internal "formmail" feature.
'compressionLevel' => 0, // Determines output compression of FE output. Makes output smaller but slows down the page generation depending on the compression level. Requires zlib in your PHP4 installation. Range 1-9, where 1 is least compression (approx. 50%) and 9 is greatest compression (approx 33%). 'true' as value will set the compression based on the system load (works with Linux, FreeBSD). Suggested value is 3. For more info, see class in t3lib/class.gzip_encode.php written by Sandy McArthur, Jr. <Leknor@Leknor.com>
'compressionDebugInfo' => 0, // Boolean. If set, then in the end of the pages, the sizes of the compressed and non-compressed document is output. This should be used ONLY as a test, because the content is compressed twice in order to output this statistics!
'compressionLevel' => 0, // Determines output compression of FE output. Makes output smaller but slows down the page generation depending on the compression level. Requires zlib in your PHP installation. Range 1-9, where 1 is least compression and 9 is greatest compression. 'true' as value will set the compression based on the PHP default settings (usually 5). Suggested and most optimal value is 5.
'pageNotFound_handling' => '', // How TYPO3 should handle requests for non-existing/accessible pages. false (default): The 'nearest' page is shown. TRUE or '1': An TYPO3 error box is displayed. Strings: page to show (reads content and outputs with correct headers), eg. 'notfound.html' or 'http://www.domain.org/errors/notfound.html'. If prefixed "REDIRECT:" it will redirect to the URL/script after the prefix (original behaviour). If prefixed with "READFILE:" then it will expect the remaining string to be a HTML file which will be read and outputted directly after having the marker "###CURRENT_URL###" substituted with REQUEST_URI and ###REASON### with reason text, for example: "READFILE:fileadmin/notfound.html". Another option is the prefix "USER_FUNCTION:" which will call a user function, eg. "USER_FUNCTION:typo3conf/pageNotFoundHandling.php:user_pageNotFound->pageNotFound" where the file must contain a class "user_pageNotFound" with a method "pageNotFound" inside with two parameters, $param and $ref
'pageNotFound_handling_statheader' => 'HTTP/1.0 404 Not Found', // If 'pageNotFound_handling' is enabled, this string will always be sent as header before the actual handling.
'pageNotFoundOnCHashError' => 0, // Boolean. If true, a page not found call is made when cHash evaluation error occurs. By default they will just disable caching but still display page output.
