As a result, many leading content delivery vendors utilize some kind of caching technology to reduce the number and size of round-trips back to databases or other repositories. One of the reasons for this is Vignette's patented caching architecture, which allows sites to behave in a highly dynamic and personalized fashion, but perform close to the speed of static web sites. Caching is integrated with Vignette's automated browser and locale detection capabilities, so that multiple variations of a component generated to support a particular browser type, character set, or country can be cached automatically and transparently, with no additional programming required. Cache management and maintenance are tightly integrated with the content management process. As static files are launched by CMS, they are automatically propagated to the correct front-line file systems, and the same processes handle their updating and expiration.
Cache maintenance is an automated task that can be interleaved into a workflow.
A single update can easily be reflected across the enterprise. Caches can be cleared and maintained at a very granular level, minimizing system load by only maintaining items that have actually changed, rather than forcing the clearing and regeneration of thousands of entire web pages.
