Breaking: #75357 - $TYPO3_CONF_VARS[BE][lockSSL] option is boolean

See Issue #75357

Description

The setting $GLOBALS[TYPO3_CONF_VARS][BE][lockSSL] which forces requests to the TYPO3 Backend to be transferred via SSL, has been changed to only allow boolean values.

The settings previously allowed three options:

  • lockSSL set to 0 - Don't force a SSL connection at all
  • lockSSL set to 1 - If the incoming request to the TYPO3 backend is a non-SSL request, an exception was thrown
  • lockSSL set to 2 - If the incoming request is a non-SSL-request, redirect to the SSL-enabled URL

The option 1 has been removed without substitution, allowing the following variants:

  • lockSSL set to false - Don't force a SSL connection at all
  • lockSSL set to true - If the incoming request is a non-SSL-request, redirect to the SSL-enabled URL

Impact

If the option was set previously to 1, the exception is not thrown but a redirect will now happen. The same behavior as the existing option 2.

Affected Installations

TYPO3 instances having the option above set to 1.
