Website Acceleration PHP class

A PHP class to easilly manage the different aspect of dealing with the WSA caching engine.

Note: Since the WSA update to 1.1.X, the administrator may hide the WSA caching header in the HTML page. Therefore, the function to verify is WSA is installed will now return an integer instead of a Boolean. A value of 0 for the module not being installed will be return and help keep backward compatibility. Added value of 1, 2 or 3 will be return depending on the information found in the page header. See the function detail for more information.

    WSAHandler\WSA::purge_cache();
