-// GetURLHandler is used to download data from |url|. When download is
-// finished or when an error occurs, it posts a message back to the browser
-// with the results encoded in the message as a string and self-destroys.
-//
-// pp::URLLoader.GetDownloadProgress() is used to to allocate the memory
-// required for url_response_body_ before the download starts.  (This is not so
-// much of a performance improvement, but it saves some memory since
-// std::string.insert() typically grows the string's capacity by somewhere
-// between 50% to 100% when it needs more memory, depending on the
-// implementation.)  Other performance improvements made as outlined in this
-// bug: http://code.google.com/p/chromium/issues/detail?id=103947
