WinCache Extension 1.1 for PHP – Beta 2

Today IIS team has published a second beta of WinCache 1.1, which has the following new features and improvements :

  • File Change Notifications – the entries in the opcode and file caches are now updated as soon as the corresponding PHP files are modified on a file system. This is very useful for PHP applications that store its configuration in PHP files – for example Joomla!. Now the configuration changes for those applications take effect right away instead of a 30 seconds delay (default cache refresh interval);
  • Persistent Session Handler – the content of the WinCache session cache is persisted on disk so that it is not lost during IIS worker process recycling.
  • Lock/Unlock API’s – these API’s can be used to obtain/release an exclusive lock on a key in the cache.

The beta builds of the extension can be downloaded and installed from the extension home page at: (look for the “WinCache 1.1 – Beta 2” section there). The source code can be obtained from The documentation for the extension can be found on PHP.NET WinCache documentation.

To learn how to change popular PHP applications to use WinCache 1.1 features refer to the following:
