This question already has an answer here:
Is the content for an auto-saved draft located on the server, or on the client/browser side?
When I'm writing a answer or question I see a small-sized text display, "draft saved" under that textarea. If I don't submit that form, my content remains in that textarea. And I will see it even after several days.
Is that text stored in the database? Or just a localstorage?
