WURFL's New API Question

I have a simple stupid question. Here's the problem, for years, my company has been using the old WURFL PHP API. Now, with the release of the new WURFL PHP API that promises a better performance, we want to use it.

What I want to ask is, how do I update the cache? Can I 开发者_运维问答use the old update_cache.php?

After several day searching for answer, it turns out that I can't use the old update_cache.php as it's incompatible to the NEW API. The new API have the auto refresh mechanism when it see the wurfl.xml is changed/updated.

If you're concerned about performance, you should look at Tera-WURFL, it was built on the new WURFL API and uses MySQL to provide extremely high device detection performance.
