; Use session locking
; valid values: On, Off
; the default is On
memcached.sess_locking = On

; Session spin lock retry wait time in microseconds.
; Be carefull when setting this value.
; Valid values are integers, where 0 is interpreted as
; the default value. Negative values result in a reduces
; locking to a try lock.
; the default is 150000

; memcached session key prefix
; valid values are strings less than 219 bytes long
; the default value is "memc.sess.key."

; memcached session binary mode
memcached.sess_binary = Off

; Set the compression type
; valid values are: fastlz, zlib
; the default is fastlz
memcached.compression_type = "fastlz"

; Compression factor
; Store compressed value only if the compression
; factor (saving) exceeds the set limit.
;
;  store compressed if:
;    plain_len > comp_len * factor
;
; the default value is 1.3 (23% space saving)

; The compression threshold
;
; Do not compress serialized values below this threshold.
; the default is 2000 bytes

; Set the default serializer for new memcached objects.
; valid values are: php, igbinary, json, json_array
;
; json - standard php JSON encoding. This serializer
;        is fast and compact but only works on UTF-8
;        encoded data and does not fully implement
;        serializing. See the JSON extension.
; json_array - as json, but decodes into arrays
; php - the standard php serializer
; igbinary - a binary serializer
;
; The default is igbinary if available and php otherwise.
