# This is the Apache server configuration file providing SSL
support.

how to

about these

# 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.

# Access Control:
# With SSLRequire you can do per-directory access

# for
more details.

# 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.

nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0
# Per-Server Logging:
# The home of a custom SSL log file. Use this
when you want a
# compact non-error SSL logfile on a virtual host
basis.
