Represents response frame that is returned from Fetch#takeResponseBodyAsStream operation call. Returns a handle to the stream representing the response body. The request must be paused in the HeadersReceived stage. Note that after this command the request can't be continued as is -- client either needs to cancel it or to provide the response body. The stream only supports sequential read, IO.read will fail if the position is specified. This method is mutually exclusive with getResponseBody. Calling other methods that affect the request or disabling fetch domain before body is received results in an undefined behavior.

Represents request frame that can be used with Network#takeResponseBodyForInterceptionAsStream operation call.

Represents response frame that is returned from Network#takeResponseBodyForInterceptionAsStream operation call. Returns a handle to the stream representing the response body. Note that after this command, the intercepted request can't be continued as is -- you either need to cancel it or to provide the response body. The stream only supports sequential read, IO.read will fail if the position is specified.
