Is it possible to save a webpage in a way that embeds the URL of the page being saved?

If I save a page to a local HTML file, I do not see where the URL of the page itself is saved. There is no comment or anything at the top that contains the URL. So I have to either add a comment manually myself or make a note of it somewhere, or bookmark it.

Is there a smarter way of working? Can the URL be derived or fished out of the saved file, or is there any feature that saves the URL as well?
