Server certificates

In order for the server to be able to connect certificates, you must add at least one address, after which the server will check the host, and also check, maybe this host is in the certificate folder of the "Websites" application. If certificates are not found, you must specify them yourself. The server works with .crt, .key and .pem certificates.
