AFAIK, the main browser process handles all network communications.
Consider the case renderer process need to fetch CSS, JavaScript or Image resource from Internet, it sends IPC ResourceMessage to the main process, the later then makes HTTP request to fetch resource. So, how those resource could be accessible from WebKit code in renderer process?

@Eric:
Your link is about how 'renderer' process ask 'main' process to do network task.
My question is about the data sharing model in Chromium that make the content fetched by 'main' process (html, javascript, css, images,...) available to that 'renderer' process.

Which is, very succinctly, indicated in that doc.
If you take a look at ResourceDispatcherHostimpl, which in turn uses Sync/AsyncResourceHandler you will see the actual shared memory buffers being transferred via IPC in the browser->renderer direction.
If you follow the IPC messages you will see how they are consumed in the renderer side.
