+Feature: #85719 - Allow sites without scheme or domain
+======================================================
+
+See :issue:`85719`
+
+Description
+===========
+
+Since the inception of site handling, the definition of a site base - the URL prefix - was limited to
+only allow a full URI with scheme (HTTP/HTTPS) and domain. This didn't allow to run TYPO3 on multiple
+domains, basically limiting the URL-resolving ("Site Routing") compared to previous URL handling
+solutions in the past.
+
+A new site routing based on symfony/routing component allows to have a flexible routing based on
+specific schemes.
+
+
+Impact
+======
+
+It is now possible to set a site base prefix to just "/site1" and "/site2" or "www.mydomain.com" instead
+of entering a full URI.
+
+This allows to have a Site base e.g. `www.mydomain.com` to be detected with http and https protocols,
+although it is recommended to do a HTTP to HTTPS redirect either on the webserver level, via a
+.htaccess rewrite rule, or by adding a redirect in TYPO3.
+
+Please also note that this improved flexibility will introduce side-effects when having multiple sites
+with mixed configuration settings as Site base:
+
+- Site 1: `/mysite/`
+- Site 2: `www.mydomain.com`
+
+will be unspecific when detecting a URL like `www.mydomain/mysite/` and can lead to side-effects.
+
+In this case, it is necessary by the Site Administrator to define unique Site base prefixes.
