README

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 which, for example, cause it to happen on the home page where there is always a trailing slash.

You can configure a suffix like .html or / for each URL, and have additional enhancers for plugins.

This extension works in a straightforward way to remove trailing slashes from:

• All generated links
• All canonical URLs
• HrefLang tags

It even redirects incoming URLs with a trailing slash to the same URL without one.

Configuration

Install the extension and ensure that all your site configuration bases 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.

Caveats

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

• Redirects will only work on GET or HEAD requests.

Pending Issues

• 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.
