README

TYPO3 has a built-in error handling system which sends 50x HTTP response codes when a PHP error or syntax error occurred, or an unhandled PHP Exception is sent.

This is perfect for really 99.9999% of the use-cases, however when using TYPO3 behind a CDN with a singular domain and various other systems, a CDN could be configured to treat 50x status codes as a bug for the whole domain, effectively blocking all access to the domain / zone.

For this reason, this extension is created which transfers 50x HTTP status codes to a 400 error code before emitting the result to the browser.

Installation

Install the extension via composer:

composer req b13/evergreen-errors

Then configure your TYPO3 installation to use the exception handler, by setting the productionExceptionHandler in your typo3conf/LocalConfiguration.php or typo3conf/AdditionalConfiguration.php file.

Here is an example for your AdditionalConfiguration.php / additional.php file:

$GLOBALS['TYPO3_CONF_VARS']['SYS']['productionExceptionHandler'] = \B13\EvergreenErrors\EvergreenExceptionHandler::class;

If you also want to enable this for your debug exception handler, use

$GLOBALS['TYPO3_CONF_VARS']['SYS']['debugExceptionHandler'] = \B13\EvergreenErrors\EvergreenDebugExceptionHandler::class;
