Valid Values
■
none
: disables the global/interprocess session cache.
Produces no impact on functionality, but makes a major
difference in performance.
■
shmht: /path/to/datafile[bytes]
: Uses a
high-performance hash table (
bytes
specifies approximate
size) inside a shared memory segment in RAM, which is
established by the
/path/to/datafile

synchronizes the local SSL memory caches of the server
processes.
■
shmcb: /path/to/datafile[bytes]
: Uses a
high-performance Shared Memory Cyclic Buffer (SHMCB)
session cache to synchronize the local SSL memory caches
of the server processes. The performance of
shmcb
is more
uniform in all environments when compared to
shmht
.
