## ## SSL Global Context ## ## All SSL configuration in this context applies both to ## the main server and all SSL-enabled virtual hosts. ## # These are the configuration directives to instruct the server how to # serve pages over an https connection. For detailing information about these # directives see # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # This global SSL configuration is ignored if # "SSL" is not defined, or if "NOSSL" is defined. # # Some MIME-types for downloading Certificates and CRLs # AddType application/x-x509-ca-cert .crt AddType application/x-pkcs7-crl .crl # Pass Phrase Dialog: # Configure the pass phrase gathering process. # The filtering dialog program (`builtin' is a internal # terminal dialog) has to provide the pass phrase on stdout.
