// This file contains an implementation of the ResourceLoaderBridge class.
// The class is implemented using URLRequest, meaning it is a "simple" version
// that directly issues requests. The more complicated one used in the
// browser uses IPC.
//
// Because URLRequest only provides an asynchronous resource loading API, this
// file makes use of URLRequest from a background IO thread. Requests for
// cookies and synchronously loaded resources result in the main thread of the
// application blocking until the IO thread completes the operation. (See
// GetCookies and SyncLoad)
//
// Main thread IO thread
// ----------- ---------
// ResourceLoaderBridge <---o---------> RequestProxy (normal case)
// \ -> URLRequest
// o-------> SyncRequestProxy (synchronous case)
// -> URLRequest
// SetCookie <------------------------> CookieSetter
// -> net_util::SetCookie
// GetCookies <-----------------------> CookieGetter
// -> net_util::GetCookies
//
// NOTE: The implementation in this file may be used to have WebKit fetch
// resources in-process. For example, it is handy for building a single-
// process WebKit embedding (e.g., test_shell) that can use URLRequest to
// perform URL loads. See renderer/resource_dispatcher.h for details on an
// alternate implementation that defers fetching to another process.
