This tool can be used to connect to an arbitrary WebTransport server. It has several limitations:
  • It can only send an entirety of a stream at once. Once the stream is opened, all of the data is immediately sent, and the write side of the steam is closed.
  • This tool does not listen to server-initiated bidirectional streams.
  • Stream IDs are different from the one used by QUIC on the wire, as the on-the-wire IDs are not exposed via the Web API.
  • The WebTransport object can be accessed using the developer console viacurrentTransport.
