# Important: #97111 - Default URI scheme {#important-97111-1657214951}

See [forge#97111](https://forge.typo3.org/issues/97111)

## Description {#description}

Several places in the TYPO3 Core fall back to using `http` as a protocol for
links in case none was given. In order to adjust this behavior the new
`$GLOBALS['TYPO3_CONF_VARS']['SYS']['defaultScheme']` setting has been
introduced, which uses `http` as default.

In order to adjust the default protocol, one has to add the following
assignment to their `typo3conf/LocalConfiguration.php` settings:

`$GLOBALS['TYPO3_CONF_VARS']['SYS']['defaultScheme'] = 'https'`
