[TYPO3] realurl and HTTPS/SSL

[Pieter]

Hello all,

the current Typo3 version (3.8.1) requires something like:
config.baseURL = http://www.myweb.com/t3/
(with Typo3 is installed in the folder /t3) if realurl is enabled.

Problem: a page accessed with HTTPS should have:
config.baseURL = https://www.myweb.com/t3/
instead.

I need some sort of conditional typoscript statement to fix this.  Is 
there a variable available to make a conditional statement?

I'm using the https_enforcer extension to set certain pages as HTTPS.

Regards,
Pieter Verstraelen
