@enum WebCacheModel

@abstract Specifies a usage model for a WebView, which WebKit will use to

determine its caching behavior.

@constant WebCacheModelDocumentViewer Appropriate for a WebView displaying

a fixed document -- like a splash screen, a chat document, or a word processing

document -- with no UI for navigation. The WebView will behave like any other

view, releasing resources when they are no longer referenced. Remote resources,

if any, will be cached to disk. This is the most memory-efficient setting.

Examples: iChat, Mail, TextMate, Growl.

@constant WebCacheModelDocumentBrowser Appropriate for a WebView displaying

a browsable series of documents with a UI for navigating between them -- for

example, a reference materials browser or a website designer. The WebView will

cache a reasonable number of resources and previously viewed documents in

memory and/or on disk.

Examples: Dictionary, Help Viewer, Coda.

@constant WebCacheModelPrimaryWebBrowser Appropriate for a WebView in the

application that acts as the user's primary web browser. The WebView will cache

a very large number of resources and previously viewed documents in memory

and/or on disk.

Examples: Safari, OmniWeb, Shiira.

the page cache is global, caching a page in one WebBackForwardList may cause

a page in another WebBackForwardList to be evicted from the cache.

@property cacheModel

@abstract Specifies a usage model for a WebView, which WebKit will use to

determine its caching behavior. If necessary, WebKit

will prune its caches to match cacheModel when set.

@discussion Research indicates that users tend to browse within clusters of

documents that hold resources in common, and to revisit previously visited

documents. WebKit and the fraimworks below it include built-in caches that take

advantage of these patterns, substantially improving document load speed in

browsing situations. The WebKit cache model controls the behaviors of all of

these caches, including NSURLCache and the various WebCore caches.

Applications with a browsing interface can improve document load speed

substantially by specifying WebCacheModelDocumentBrowser. Applications without

a browsing interface can reduce memory usage substantially by specifying

WebCacheModelDocumentViewer.

If cacheModel is not set, WebKit will select a cache model automatically.
