Web Content Cache Types

 

Basic Web Content Caching

This is the simplest caching option. The first time a Web Page is rendered by the Web Content Management application, it is stored in a Cache. Users then access this page from the Cache until it expires. Only then is the Web Page rendered afresh. The main benefit of this scenario is improved performance. Basic Caching should only be used on static Content that does not require "real-time" access.

 

Advanced Web Content Caching

There are two major differences between Basic Caching and Advanced Caching:

1. Advanced Caching can cache pages based on different User profiles.

2. Cache parameters in "Connect" tags and URL requests can be used to override your Server's default Advanced Web Content Caching settings allowing you to set Custom Cache settings for individual Web Pages or Components.

There are five Advanced Caching types:

Site Caching	This is the same as the Basic Web Content Cache except that Cache parameters in "Connect" tags and URL requests can be used to override your Server's default Advanced Web Content Caching settings.
Session Caching	When Session Caching is enabled, a copy of each Web Page a User visits is stored in the Session Cache. The User accesses the cached version of a Web Page until they start a new session, or until the cached Web Page is expired from the cache.
User Caching	When User Caching is enabled, a copy of each Web Page a User visits is stored in the User Cache. The User accesses the cached version of a Web Page until the cached Web Page is expired from the cache.
Secured Caching	Secured Caching is used on Sites where the item Security features are used to grant different Users access to different Web Pages and Components based on the Groups they belong to.
Personalized Caching	Personalized Caching is used to cache Web Pages of Users who have the same "personalization profile". This means that Users who have selected the same personalization categories and keywords, and who belong to the same Group, share a single cache.

 

Default Web Content Caching versus Custom Caching

Cache parameters in "Connect" tags and URL requests can be used to override your Server's default Advanced Web Content Caching settings allowing you to set Custom Cache settings for individual Web Pages or Components.

In most cases, Basic, Site and Session Caching would only be used as your Server's default Web Content Cache. User, Secured and Personalized Caching would mostly be used when using Custom Caching in "Connect" tags and URL requests.

Note that if Basic Caching is used as your default Web Content Cache, Custom Caching cannot be used.

See Web Content Cache Configuration and Using Custom Caching for further information.
