This guide shows you how to use
Chrome DevTools
to inspect
Application Cache resources.
View Application Cache Data
Click the
Sources
tab to open the
Sources
panel. The
Manifest
pane usually opens
by default.
Expand the
Application Cache
section and click a cache to view its resources.
Each row of the table represents a cached resource.
The
Type
column represents the resource's category:
- Master
. The
manifest
attribute on the resource indicated that this cache is the resource's master.
- Explicit
. This resource was explicitly listed in the manifest.
- Network
. The manifest specified that this resource must come from the network.
- Fallback
. The URL is a fallback for another resource. The URL of the other resource is not listed in DevTools.
At the bottom of the table there are status icons indicating your network
connection and the status of the Application Cache. The Application Cache
can have the following statuses:
- IDLE
. The cache has no new changes.
- CHECKING
. The manifest is being fetched and checked for updates.
- DOWNLOADING
. Resources are being added to the cache.
- UPDATEREADY
. A new version of the cache is available.
- OBSOLETE
. The cache is being deleted.
