{# This file configures apache to redirect requests from ports to specific urls.
 # It provides SSL support for server and optionaly for client.
 #
 # All parameters are given through the `parameter_dict` variable, see the
 # list entries :
 #
 #     parameter_dict = {
 #       #  The path given to "PidFile"
 #       "pid-file": "<file_path>",
 #
 #       #  The number given to "TimeOut"
 #       "timeout": 300,
 #
 #       #  The path given to "SSLCertificateFile"
 #       "cert": "<file_path>",
 #
 #       #  The path given to "SSLCertificateKeyFile"
 #       "key": "<file_path>",
 #
 #       #  The value given to "SSLCipherSuite" (can be empty)

 #       "ssl-session-cache": "<folder_path>",
 #
 #       #  The path given to "SSLCACertificateFile" (can be empty)
 #       #  If this value is not empty, it enables client certificate check.
 #       #  (Enabling "SSLVerifyClient require")
 #       "ca-cert": "<file_path>",
 #
 #       #  The path given to "SSLCARevocationFile" (used if ca-cert is not
 #       #  empty)
 #       "crl": "<file_path>",
 #
 #       #  The path given to "ErrorLog"
 #       "error-log": "<file_path>",
 #
 #       #  The path given to "AccessLog"
 #       "access-log": "<file_path>",
 #
 #       #  The list of ip which apache will listen to.
 #       "ip-list": [
 #         "0.0.0.0",
 #         "[::1]",
 #       ],
 #
 #       #  The list of backends which apache should redirect to.
 #       "backend-list": [
 #         # (port, unused, internal_scheme)
 #         (8000, _, "http://10.0.0.10:8001"),

 #       ],
 #     }
 #
 # This sample of `parameter_dict` will make apache listening to :
 # - 0.0.0.0:8000 redirecting internaly to http://10.0.0.10:8001
 # - [::1]:8000 redirecting internaly to http://10.0.0.10:8001
 # - 0.0.0.0:8002 redirecting internaly to http://10.0.0.10:8003
 # - [::1]:8002 redirecting internaly to http://10.0.0.10:8003
