[SOLVED] How to handle "non-https" (http) sites in https TYPO3 backend

Issue

We run a TYPO3 multidomain system and added https support to our TYPO3 domain [typo3domain]. All other domains still run without https support (http only).

https works perfect for [typo3domain]. Redirect of all non https request to TYPO3 backend (lockSSL) works perfect as well. [typo3domain]/typo3 redirects automatically to https://[typo3domain]/typo3

Now our problem: If a editor [domain1] edits some content on https://[typo3domain]/typo3 and goes to page -> view page then https://[domain1] is called, but this does not work (invalid certificate), because [domain1] is a non ssl domain.

How can i fix this?


Solution

You can set the preview domain in the root page TSconfig of the non-https sites, including the protocol:

TCEMAIN.previewDomain = http://domain1

More on this option can be found here: https://docs.typo3.org/typo3cms/TSconfigReference/PageTsconfig/TceMain.html#previewdomain
