Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Wraps the network request/response interception, providing thread-safety guarantees and handling special cases such as browser canceling requests midst interception.

You should not be using this class directly, use Driver#intercept instead.
