I understand that the Chrome warning “Uncommon Download” is widely based on how common the download is, but what are the specific conditions?
Is “routine” measured or heuristic? (for example, "zip files are always considered not common")
If it is measured, is it based on a domain, protocol (e.g. http or dataurl), or the full specific URL?
It is clear that the file or content type is one of them. On the same website, I saw that the zip file triggers a warning, while PNG or JPG will not. Is there any way to do this without initiating the creation of the zip file and saving it through JSZip?
