Caching in UltimateTemplateEngine

With ComponentSoft Template Engine, you can easily cache your loaded template data to speed up your application performance by using two events in TemplateEngine class, as shown below:

* Uses OnLoadTemplateFromCache for loading cached template data.
* Uses OnSaveTemplateToCache for saving template data to cache.

The Web Sample code-behind below shows how to load/save template data from/to Http Cache.
