##  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 <URL:http://httpd.apache.org/docs-2.2/mod/mod_ssl.html>
#
# 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.

	#   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.

	#   Inter-Process Session Cache:
	#   Configure the SSL Session Cache: First the mechanism 
	#   to use and second the expiring timeout (in seconds).
	#   shm means the same as shmht. 
	#   Note that on most platforms shared memory segments are not allowed to be on 
	#   network-mounted drives, so in that case you need to use the dbm method.

	#   Pseudo Random Number Generator (PRNG):
	#   Configure one or more sources to seed the PRNG of the 
	#   SSL library. The seed data should be of good random quality.
	#   WARNING! On some platforms /dev/random blocks if not enough entropy
	#   is available. This means you then cannot use the /dev/random device
	#   because it would lead to very long connection times (as long as
	#   it requires to make more entropy available). But usually those
	#   platforms additionally provide a /dev/urandom device which doesn't
	#   block. So, if available, use this one instead. Read the mod_ssl User
	#   Manual for more details.
