Analyzing page resources
The Resources panel
You can click the Resources icon on the toolbar to display the Resources panel.
Resources panel displays a complete list of the resources that the WebKit engine must request and load to render the webpage, as well as any client-side resources created and used by the web page. You can also use the Resources panel to view the content of any resource file. Resources are organized in the panel into the following categories:
- Frames: Contains the resources for each frame displayed in the content, including images, fonts, scripts, stylesheets, and other content resources, such as embedded video or Flash files. Subframes within the main window are displayed as subfolders beneath the main Frames folder.
- Databases: Contains all the database tables that are associated with your content or app.
- Local Storage: Contains all Local Storage objects, that is, storage objects which persist after a browser session has ended.
- Session Storage: Contains all Session Storage objects, that is, storage objects which are only valid for the current browser session.
- Cookies: Contains all the cookies associated with the webpage or app.
- Application Cache: Contains the resources included in the manifest of an offline web application.
