 106         #   SSL Engine Options:

 108         #   o FakeBasicAuth:
 109         #     Translate the client X.509 into a Basic Authorisation.  This means that
 110         #     the standard Auth/DBMAuth methods can be used for access control.  The
 111         #     user name is the `one line' version of the client's X.509 certificate.
 112         #     Note that no password is obtained from the user. Every entry in the user
 113         #     file needs this password: `xxj31ZMTZzkVA'.
 114         #   o ExportCertData:
 115         #     This exports two additional environment variables: SSL_CLIENT_CERT and
 116         #     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
 117         #     server (always existing) and the client (only existing when client
 118         #     authentication is used). This can be used to import the certificates
 119         #     into CGI scripts.
 120         #   o StdEnvVars:
 121         #     This exports the standard SSL/TLS related `SSL_*' environment variables.
 122         #     Per default this exportation is switched off for performance reasons,
 123         #     because the extraction step is an expensive operation and is usually
 124         #     useless for serving static content. So one usually enables the
 125         #     exportation for CGI and SSI requests only.
 126         #   o StrictRequire:
 127         #     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
 128         #     under a "Satisfy any" situation, i.e. when it applies access is denied
 129         #     and no other module can change it.
 130         #   o OptRenegotiate:
 131         #     This enables optimized SSL connection renegotiation handling when SSL
 132         #     directives are used in per-directory context.

 141         #   SSL Protocol Adjustments:
 142         #   The safe and default but still SSL/TLS standard compliant shutdown
 143         #   approach is that mod_ssl sends the close notify alert but doesn't wait for
 144         #   the close notify alert from client. When you need a different shutdown
 145         #   approach you can use one of the following variables:
 146         #   o ssl-unclean-shutdown:
 147         #     This forces an unclean shutdown when the connection is closed, i.e. no
 148         #     SSL close notify alert is send or allowed to received.  This violates
 149         #     the SSL/TLS standard but is needed for some brain-dead browsers. Use
 150         #     this when you receive I/O errors because of the standard approach where
 151         #     mod_ssl sends the close notify alert.
 152         #   o ssl-accurate-shutdown:
 153         #     This forces an accurate shutdown when the connection is closed, i.e. a
 154         #     SSL close notify alert is send and mod_ssl waits for the close notify
 155         #     alert of the client. This is 100% SSL/TLS standard compliant, but in
 156         #     practice often causes hanging connections with brain-dead browsers. Use
 157         #     this only for browsers where you know that their SSL implementation
 158         #     works correctly.
 159         #   Notice: Most problems of broken clients are also related to the HTTP
 160         #   keep-alive facility, so you usually additionally want to disable
 161         #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
 162         #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
 163         #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
 164         #   "force-response-1.0" for this.
