network::URLLoaderFactory / URLLoader

The source provides a highly technical overview of the Chromium Network Stack Architecture and Request Pipeline, detailing how network requests are processed from initiation to completion. It explains that the browser utilizes a dedicated Network Service (often in a separate process) for handling requests through objects like the mojom::URLLoaderFactory and network::URLLoader. The document then describes the layered pipeline within the //net stack, focusing on the role of the persistent net::URLRequest object, the caching mechanism via the HttpCache, and the HttpNetworkTransaction which manages network I/O, including connection reuse and protocol negotiation by the HttpStreamFactory. Finally, the text outlines the asynchronous flow for streaming the response body using Mojo data pipes, the handling of redirects with mandatory re-checks of policies like CORS, and the overall multi-process and multi-thread architecture designed for fault tolerance and performance.
