WinCache Session Handler

The WinCache session handler (available since
WinCache 1.1.0) can be used to configure PHP to store the session
data in shared memory session cache. Using shared memory instead of
the default file session storage helps improve performance of PHP
applications that store large amount of data in session objects.
Wincache session cache uses file-backed shared memory, which
ensures that the session data is not lost during recycling of IIS
application pools.

To configure PHP to use WinCache session handler
set the php.ini setting session.save_handler to wincache. By default the Windows temporary file
location is used for storing the session data. To change the
location of the session file use session.save_path directive.

session.save_handler = wincache
session.save_path = C:\inetpub\temp\session\
