/// - It needs to appear to the browser to be a document in the book's folder. This allows local

/// the images. (We previously did this by making a file elsewhere and setting the 'base'
/// for interpreting urls. But this fails for internal hrefs (starting with #)).
/// - We don't want to risk leaving junk page files in the real book folder if anything goes wrong.
/// - There may be several of these simulated pages around at the same time (e.g., when the thumbnailer is

/// - The simulated files need to hang around for an unpredictable time (until the browser is done
/// with them).
/// The solution we have adopted is to make this server simulate files in the book folder.
/// That is, the src for the page iframe is set to a localhost: url which maps to a file in the
