External cache group settings
Use this page to configure sets of external caches controlled by WebSphere Application Server on Web servers, such as IBM Edge Server and IBM HTTP Server.
To view this administrative console page, click Servers > Application servers > servername > Container services > Dynamic cache service > External cache groups > external_cache_group.
Configuration tab
- Name
Specifies the external cache group name.
The external cache group name must match the ExternalCache property as defined in the servlet or Java Server Pages (JSP) cachespec.xml file.
When external caching is enabled, the cache matches pages with its Universal Resource Identifiers (URIs) and pushes matching pages to the external cache. The entries can then be served from the external cache, instead of the application server. This ability creates a significant savings in performance.
