                #        file needs this password: `xxj31ZMTZzkVA'.
                #   o ExportCertData:
                #        This exports two additional environment variables: SSL_CLIENT_CERT and

                #        server (always existing) and the client (only existing when client
                #        authentication is used). This can be used to import the certificates
                #        into CGI scripts.
                #   o StdEnvVars:
                #        This exports the standard SSL/TLS related `SSL_*' environment variables.
                #        Per default this exportation is switched off for performance reasons,
                #        because the extraction step is an expensive operation and is usually
                #        useless for serving static content. So one usually enables the
                #        exportation for CGI and SSI requests only.
                #   o OptRenegotiate:
               #        This enables optimized SSL connection renegotiation handling when SSL
                #        directives are used in per-directory context.

                #   SSL Protocol Adjustments:
                #   The safe and default but still SSL/TLS standard compliant shutdown
                #   approach is that mod_ssl sends the close notify alert but doesn't wait for
                #   the close notify alert from client. When you need a different shutdown
                #   approach you can use one of the following variables:
                #   o ssl-unclean-shutdown:
                #        This forces an unclean shutdown when the connection is closed, i.e. no
                #        SSL close notify alert is send or allowed to received.  This violates
                #        the SSL/TLS standard but is needed for some brain-dead browsers. Use
                #        this when you receive I/O errors because of the standard approach where
                #        mod_ssl sends the close notify alert.
                #   o ssl-accurate-shutdown:
                #        This forces an accurate shutdown when the connection is closed, i.e. a
                #        SSL close notify alert is send and mod_ssl waits for the close notify
                #        alert of the client. This is 100% SSL/TLS standard compliant, but in
                #        practice often causes hanging connections with brain-dead browsers. Use
                #        this only for browsers where you know that their SSL implementation
                #        works correctly.
                #   Notice: Most problems of broken clients are also related to the HTTP
                #   keep-alive facility, so you usually additionally want to disable
                #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
                #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
                #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
                #   "force-response-1.0" for this.
                # BrowserMatch "MSIE 2-6" \
                #               nokeepalive ssl-unclean-shutdown \
                #               downgrade-1.0 force-response-1.0

                #        Per default this exportation is switched off for performance reasons,

                #   SSL Protocol Adjustments:
                #   The safe and default but still SSL/TLS standard compliant shutdown
                #   approach is that mod_ssl sends the close notify alert but doesn't wait for
                #   the close notify alert from client. When you need a different shutdown
                #   approach you can use one of the following variables:
                #   o ssl-unclean-shutdown:
                #        This forces an unclean shutdown when the connection is closed, i.e. no
                #        SSL close notify alert is send or allowed to received.  This violates
                #        the SSL/TLS standard but is needed for some brain-dead browsers. Use
                #        this when you receive I/O errors because of the standard approach where
                #        mod_ssl sends the close notify alert.
                #   o ssl-accurate-shutdown:
                #        This forces an accurate shutdown when the connection is closed, i.e. a
                #        SSL close notify alert is send and mod_ssl waits for the close notify
                #        alert of the client. This is 100% SSL/TLS standard compliant, but in
                #        practice often causes hanging connections with brain-dead browsers. Use
                #        this only for browsers where you know that their SSL implementation
                #        works correctly.
                #   Notice: Most problems of broken clients are also related to the HTTP
                #   keep-alive facility, so you usually additionally want to disable
                #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
                #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
                #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
                #   "force-response-1.0" for this.
                # BrowserMatch "MSIE 2-6" \
                #               nokeepalive ssl-unclean-shutdown \
