The LSCache module can activate and manage the LSCache functions of a LiteSpeed Web Server. It will only work if your site is running on a LiteSpeed Web Server using either OpenLiteSpeed or LiteSpeed Enterprise. The module was inspired by trying to chase down a nice high Google PageSpeed score.

The LiteSpeed Web Server LSCache function does a great job of caching the finished HTML pages – but you need to be able to turn it off & refresh the cache when pages are updated in CMS Made Simple.

With the LSCache module activated, caching is paused whenever a user logs into the CMS Admin Console. Caching is paused for 30 minutes after login and after any Content Manager page is saved. Caching is reactivated when a user logs out of the CMS or 30 minutes after login/page save (in case the user doesn't log out).

Currently, all pages are cached. If some site pages include dynamic elements such as a shopping cart or basket the LSCache module should not be activated. Future versions will include Edge Side Includes (ESI) so that dynamic or user-specific content will not be cached.

So … did the Google PageSpeed improve – Yes, definitely. Without caching a target site was generally loading in 1 second, with LSCache enabled, this dropped to around .45 second. The key improvement was with the TTFB (Time to First Byte) dropping from 360ms to 32ms. Check it out:
