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.

Example #1 Enabling WinCache session handler

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