A content group is a container for cached objects that can be served in a response. When you first enable the integrated cache, cacheable objects are stored in a content group named Default. You can create new content groups that have unique properties. For example, you can define separate content groups for image data, bug reports, and stock quotes, and you can configure the stock quote content group to be refreshed more often than the other groups.
You can configure expiration of an entire content group or selected entries in a content group.
The data in a content group can be static or dynamic, as follows:
For example, the content group can retrieve responses that match NameField=username and BugID=ID.
For example, an invalidation selector can find responses that match NameField=username and BugID=ID.
