This type is a string, which represents the context in which a resource was fetched in a web request.
It's used to filter the requests you listen to using the webRequest API. For example: you can listen to requests only for images, or only for scripts.
Note: This API is based on Chromium's chrome.webRequest
API. This documentation is derived from web_request.json
in the Chromium code.
