I discovered some new behavoir with 2.3. I have a search form on the page. If I search for something SStripe automatically switches to https on form submit.
For me, this is a problem, the https is a proxy to the webmail. So a search request is answered by a webmail login prompt. How can I force SStripe to stay on http?
Found the cause. My bad. Misconfiguration in the Webserver. /home was redirected to https, since it is also used by webmail. Had an exception for the search results, but not for the search form itself
