# info: adding ssl for domain
# options: user domain ssl_dir [ssl_home] [restart]
#
# The function turns on SSL support for a domain. Parameter ssl_dir is a path
# to directory where 2 or 3 ssl files can be found. Certificate file 
# domain.tld.crt and its key domain.tld.key  are mandatory. Certificate
# authority domain.tld.ca file is optional. If home directory  parameter
# (ssl_home) is not set, https domain uses public_shtml as separate
# documentroot directory.
