Never miss a Slash in your TYPO3 URLs

Whether you configure a page type to end in a slash or not, TYPO3 will always allow you to access the page with or without a trailing slash. This can lead to duplicate content issues, and is generally not a good idea.

This extension will redirect any URL that does not end in a slash to the same URL with a slash if the current page type is configured like this.

Configuration

Install the extension. It will look for any page types in the site configuration, that are configured to end in a slash.

routeEnhancers:
  PageTypeSuffix:
    type: PageType
    default: /
    index: ''
    map:
      /: 0

For these page types, any URL that has a path, that does not end in a slash will be redirected to the same path with a slash.
