# Module: bdb_tables
# Description:
#	Add support for Berkeley DB based lookup tables. The format for 
#	bdb path of the lookup table is:
#		bdb:/path/to/bdb[{param1=val, ...}]
#	bdb table parameters can be one or more of the followings:
#	    cache-size=Size[K|M]
#               The cache size to use. Default is the berkeleyDB default value.
#	    cache-num=num
#	        The number of caches to create. The cache will be split across
#	        num separate regions, where the region size is equal to the
#	        initial cache size divided by ncache.
#	Use the c-icap-mkbdb utility to build Berkeley DB c-icap lookup tables
# Example:
#	Module common bdb_tables.so

# End module: bdb_tables

# Module: dnsbl_tables
# Description:
#	Add support for dns lookup tables. Can be used to access
#	dns block lists. The dnsbl lookup table path definition is:
#	    dnsbl:domainname[{param1=val, ...}]
#       dnsbl table parameters can be one or more of the followings:
#            cache=no|cache_type
#               The cache type to use or 'no' for no cache.
#            cache-size=Size[K|M]
#               The cache size in RAM
#            cache-ttl=ttl
#               The cache ttl to use
#	
#	For example the lookup table  for accessing the black.uribl.com
#	dns black list is: 
#	    dnsbl:black.uribl.com
# Example:
#	Module common dnsbl_tables.so

# End module: dnsbl_tables

# Module: ldap_module
# Description:
#	Add LDAP support to c-icap. The user can use LDAP based lookup tables
#	using the following lookup table paths:
#	      ldap://[username:password@]ldapserver?base?attr1,attr2?filter[{[param=value, ...]}]
#	      ldaps://...
#	      ldapi://...
#	The filter can contain the "%s" formating code which will be replaced by
#	the search key.
#	ldap table parameters can be one or more of the followings:
#	     name=aName
#		A unique name to use for this table
#	     cache=no|cache_type
#		The cache type to use or no for no cache.
#	     cache-size=Size[K|M]
#		The cache size in RAM
#	     cache-ttl=ttl
#		The cache ttl to use
#	     cache-item-size=ItemSize[K|M]
#		The maximum item size
#	
#	Examples of supported ldap urls:
#	     ldap://ldap.chtsanti.net?o=chtsanti?cn,uid?uid=%s{cache=memcached}
#	     ldap://cn=Directory Manager:Apassword@ldap.chtsanti.net?o=chtsanti?mermberUid?(&(objectClass=posixGroup)(cn=%s))
#	
#	WARNING: is not enough tested it may contain bugs!
# Example:
#	Module common ldap_module.so

# End module: ldap_module

# Module: memcached
# Description:
#       Add support for memcached c-icap cache.

#       Module common memcached.so

# TAG: memcached.servers
# Format: memcached.servers hostname1 hostname2 ...
# Description:
#	Set the memcached servers to use
# Default:
#	memcached.servers 127.0.0.1

# TAG: memcached.use_md5_keys
