### Constants

[`WebCacheModel.documentViewer`](/documentation/WebKit/WebCacheModel/documentViewer)

Releases resources when they are no longer referenced and caches remote resources on disk. This model is appropriate for displaying a static document with no navigation user interface. This is the most memory-efficient model.

[`WebCacheModel.documentBrowser`](/documentation/WebKit/WebCacheModel/documentBrowser)

Caches a reasonable number of resources and previously viewed documents in memory and on disk. This model is appropriate for displaying and navigating between multiple documents.

[`WebCacheModel.primaryWebBrowser`](/documentation/WebKit/WebCacheModel/primaryWebBrowser)

Caches a large number of resources and previously viewed documents in memory and on disk. This model is appropriate for a web view that behaves like a web browser.
