-// This file contains an implementation of the ResourceLoaderBridge class.
-// The class is implemented using net::URLRequest, meaning it is a "simple"
-// version that directly issues requests. The more complicated one used in the
-// browser uses IPC.
-//
-// Because net::URLRequest only provides an asynchronous resource loading API,
-// this file makes use of net::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)
-//                           \            -> net::URLRequest
-//                            o-------> SyncRequestProxy (synchronous case)
-//                                        -> net::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 net::URLRequest to
-// perform URL loads.  See renderer/resource_dispatcher.h for details on an
-// alternate implementation that defers fetching to another process.
