[otrs] OTRS https

Dear All, First, thank you all for the answers you sent to my questions. Everything is not set for the moment and maybe I will continue my last questions... But now, I have a configuration problem. I would like to make OTRS accessible under https (it's under Linux)... I did certificates and if I type https://otrsservername, I can connect and all is under https (certificate). But if I type http://otrsservername, I can also connect, but without certificate. How could I make a redirection when I type http to https? Is it under httpd or under OTRS? Which file(s) Many thanks in advance and have a nice day, Philippe Roth, Switzerland
