Bug 281936

Spec: https://w3c.github.io/webdriver-bidi/#module-network Test dashboard: https://wpt.fyi/results/webdriver/tests/bidi/network?label=experimental&label=master&aligned Given the complexity of the methods, we'll likely implement them as separate patches. Commands: - network.addIntercept - https://w3c.github.io/webdriver-bidi/#command-network-addIntercept - network.continueRequest - https://w3c.github.io/webdriver-bidi/#command-network-continueRequest - network.continueResponse - https://w3c.github.io/webdriver-bidi/#command-network-continueResponse - network.continueWithAuth - https://w3c.github.io/webdriver-bidi/#command-network-continueWithAuth - network.failRequest - https://w3c.github.io/webdriver-bidi/#command-network-failRequest - network.provideResponse - https://w3c.github.io/webdriver-bidi/#command-network-provideResponse - network.removeIntercept - https://w3c.github.io/webdriver-bidi/#command-network-removeIntercept - network.setCacheBehavior - https://w3c.github.io/webdriver-bidi/#command-network-setCacheBehavior Events: - network.authRequired - https://w3c.github.io/webdriver-bidi/#event-network-authRequired - network.beforeRequestSent - https://w3c.github.io/webdriver-bidi/#event-network-beforeSendRequest - network.fetchError - https://w3c.github.io/webdriver-bidi/#event-network-fetchError - network.responseCompleted - https://w3c.github.io/webdriver-bidi/#event-network-responseCompleted - network.responseStarted - https://w3c.github.io/webdriver-bidi/#event-network-responseStarted The module also defines a number of data types[1] for the method/event parameters, like network.Request, network.Header.
