		#   SSL Engine Switch:
		#   Enable/Disable SSL for this virtual host.
		SSLEngine on
		#   A self-signed (snakeoil) certificate can be created by installing
		#   the ssl-cert package. See
		#   /usr/share/doc/apache2.2-common/README.Debian.gz for more info.
		#   If both key and certificate are stored in the same file, only the
		#   SSLCertificateFile directive is needed.
		SSLCertificateFile    /etc/ssl/certs/ssl-cert-snakeoil.pem
		SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
		#   Server Certificate Chain:
		#   Point SSLCertificateChainFile at a file containing the
		#   concatenation of PEM encoded CA certificates which form the
		#   certificate chain for the server certificate. Alternatively
		#   the referenced file can be the same as SSLCertificateFile
		#   when the CA certificates are directly appended to the server
		#   certificate for convinience.
		#SSLCertificateChainFile /etc/apache2/ssl.crt/server-ca.crt
		#   Certificate Authority (CA):
		#   Set the CA certificate verification path where to find CA
		#   certificates for client authentication or alternatively one
		#   huge file containing all of them (file must be PEM encoded)
		#   Note: Inside SSLCACertificatePath you need hash symlinks
		#         to point to the certificate files. Use the provided
		#         Makefile to update the hash symlinks after changes.
		#SSLCACertificatePath /etc/ssl/certs/
		#SSLCACertificateFile /etc/apache2/ssl.crt/ca-bundle.crt
		#   Certificate Revocation Lists (CRL):
		#   Set the CA revocation path where to find CA CRLs for client
		#   authentication or alternatively one huge file containing all
		#   of them (file must be PEM encoded)
		#   Note: Inside SSLCARevocationPath you need hash symlinks
		#         to point to the certificate files. Use the provided
		#         Makefile to update the hash symlinks after changes.
		#SSLCARevocationPath /etc/apache2/ssl.crl/
		#SSLCARevocationFile /etc/apache2/ssl.crl/ca-bundle.crl
		#   Client Authentication (Type):
		#   Client certificate verification type and depth.  Types are
		#   none, optional, require and optional_no_ca.  Depth is a
		#   number which specifies how deeply to verify the certificate
		#   issuer chain before deciding the certificate is not valid.
		#SSLVerifyClient require
		#SSLVerifyDepth  10
		#   Access Control:
		#   With SSLRequire you can do per-directory access control based
		#   on arbitrary complex boolean expressions containing server
		#   variable checks and other lookup directives.  The syntax is a
		#   mixture between C and Perl.  See the mod_ssl documentation
		#   for more details.
		#<Location />
		#SSLRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
		#            and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
		#            and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"} \
		#            and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
		#            and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20       ) \
		#           or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
		#   SSL Engine Options:
		#   Set various options for the SSL engine.
		#   o FakeBasicAuth:
		#     Translate the client X.509 into a Basic Authorisation.  This means that
		#     the standard Auth/DBMAuth methods can be used for access control.  The
		#     user name is the `one line' version of the client's X.509 certificate.
		#     Note that no password is obtained from the user. Every entry in the user
		#     file needs this password: `xxj31ZMTZzkVA'.
		#   o ExportCertData:
		#     This exports two additional environment variables: SSL_CLIENT_CERT and
		#     SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
		#     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 StrictRequire:
		#     This denies access when "SSLRequireSSL" or "SSLRequire" applied even
		#     under a "Satisfy any" situation, i.e. when it applies access is denied
		#     and no other module can change it.
		#   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.*" \
				nokeepalive ssl-unclean-shutdown \
				downgrade-1.0 force-response-1.0
