Breaking: #70229 - BE-lockSSL = 3 option removed

See Issue #70229

Description

The global option $TYPO3_CONF_VARS[BE][lockSSL] allows to lock the backend usage to be worked completely over SSL. Setting this option to “3” allowed to have only the backend login transmitted via SSL, but the rest forced to work via plain HTTP. Option “3” has been removed in favor of having a full SSL session for all communication between the server and the client / browser.

Impact

Installations having lockSSL set to “3” will now behave just as it would be lockSSL=1.

Affected Installations

Any installation that has $TYPO3_CONF_VARS[BE][lockSSL] set to 3, only having SSL for the Backend login page.

Migration

It is recommended to set the $TYPO3_CONF_VARS[BE][lockSSL] option to 1 or 2, depending on the environment and the possibilities of having SSL available.
