Middleware

TYPO3 Middleware is like a filter for your website. When someone visits your site, the middleware checks and processes the request before it reaches your content. It can do things like check for security, handle user logins, or manage how data is shown.

Think of it as a gatekeeper that makes sure everything runs smoothly and safely. It helps keep your website fast, secure, and user-friendly. In TYPO3, middleware can be customized to fit the specific needs of your site.
