I've installed Limesurvey v1.91 behind two reverse-proxies nginx and haproxy. Nginx hosts the SSL certificate and redirects in http protocol to haproxy, which "load-balances" to the Apache servers.
HTTP and HTTPS work well but when in Nginx I redirect HTTP to HTTPS, the authentication in /admin fails : the page with the form is refreshed but no messages appears on the web page or in the logs.
Any idea for the redirect work ?
