With TYPO3, it is possible to have a trailing slash in your URLs, but also without them - depending on the use-case.

By default, TYPO3 does not have a trailing slash at the end of each URL, but there are some technical limitations, why it e.g. happens on the home page, where there is always a trailing slash.

You can configure an ending like ".html" or "/" for each URL, and have more enhancers for plugins.

This extension works in a naive way to remove trailing slashes from

• All generated links
• All your canonical URLs

It even redirects incoming URLs with a trailing slash into the same page without.

Install the extension, ensure that all your site configuration base's for languages do NOT have a trailing slash

Good: base: 'https://example.com/en' Bad: base: 'https://example.com/en/'

Good: base: '/fr' Bad: base: '/fr/'

That's it.

• Ensure that you do not have a enhancer or PageType decorator that creates URLs (also for plugins) with a trailing slash.

• Redirects will only work on GET or HEAD requests.

• How to deal with redirects from EXT:redirects
• This is currently an "all-in" solution - you can't disable this feature on a per-site basis.
