Configure RealURL¶

This step is optional. You can use this extension without RealURL.

The extension replaces your entire site template with it's own HTML templates for 404 messages. The extension uses a different pagetype from the default TYPO3 pagetype. We can use the fileName configuration option in RealURL to register our own pagetype under the filename 404.htm for example:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['realurl'] = array (
  '_DEFAULT' => array (
    'fileName' => array (
      'index' => array (
        '404.htm' => array (
          'keyValues' => array (
            'type' => 1280570199,
          ),
        ),
      ),
    ),
  ),
);

All pages using the sponsoring404 pagetype will display the 404 page. So we only need to map the pagetype to a filename of our liking. You can also use 404.html, 404.404 or something else. You will probably never see the filename directly because you will be redirected to the page when you call a non-existing URI.

Configure TYPO3 to redirect to sponsoring404¶

TYPO3 can be configured to do a redirect to a page when it can not find the page a visitor is looking for. This can be configured in the Install Tool. Under the Frontend section there is a configuration variable called: pageNotFound_handling.

You can configure this to point to our pagetype:

$TYPO3_CONF_VARS['FE']['pageNotFound_handling'] = '/?type=1280570199';

Or to the value you have configured in your RealURL configuration:

$TYPO3_CONF_VARS['FE']['pageNotFound_handling'] = '/404.htm';
