// Pass an instance of DownloadUrlParameters to DownloadManager::DownloadUrl()
// to download the content at |url|. All parameters with setters are optional.
// |referrer| and |referrer_encoding| are the referrer for the download. If
// |prefer_cache| is true, then if the response to |url| is in the HTTP cache it
// will be used without revalidation. If |post_id| is non-negative, then it
// identifies the post transaction used to originally retrieve the |url|
// resource - it also requires |prefer_cache| to be |true| since re-post'ing is
// not done.  |save_info| specifies where the downloaded file should be saved,
// and whether the user should be prompted about the download.  If not null,
// |callback| will be called when the download starts, or if an error occurs
// that prevents a download item from being created.  We send a pointer to
// content::ResourceContext instead of the usual reference so that a copy of the
// object isn't made.
