Type of Data
- things the user enters, except for credentials (form data)
- credentials
- things cached by the UA (pages, preview images, icons)
- local data stored by the server / web application (cookies, HTML5 local storage, Flash/Silverlight local storage)
- history information (bookmarks, visited URIs)
- settings specific to a site (for instance, preferences with respect to privacy, script disabling...)
Time range
Several UAs offer to restrict the clear operation to a time range such as "today" or "last week".
Site/URI
Firefox supports "forget about this site". Other UAs do not appear to support this.
