 A faster version of `Dispatcher.request`. This method expects the second argument `factory` to return a [`stream.Writable`](https://nodejs.org/api/stream.html#stream_class_stream_writable) stream which the response will be written to. This improves performance by avoiding creating an intermediate [`stream.Readable`](https://nodejs.org/api/stream.html#stream_readable_streams) stream when the user expects to directly pipe the response body to a [`stream.Writable`](https://nodejs.org/api/stream.html#stream_class_stream_writable) stream.
 
-As demonstrated in [Example 1 - Basic GET stream request](/docs/docs/api/Dispatch.md#example-1---basic-get-stream-request), it is recommended to use the `option.opaque` property to avoid creating a closure for the `factory` method. This pattern works well with Node.js Web Frameworks such as [Fastify](https://fastify.io). See [Example 2 - Stream to Fastify Response](/docs/docs/api/Dispatch.md#example-2---stream-to-fastify-response) for more details.
