Prompts the user to save the linked URL instead of navigating to it. Can be used with or without a value:
Without a value, the browser will suggest a filename/extension, generated from various sources:
The Content-Disposition HTTP header
The final segment in the URL path
The media type (from the (Content-Type header, the start of a data: URL, or Blob.type for a blob: URL)
Defining a value suggests it as the filename. / and \ characters are converted to underscores (_). Filesystems may forbid other characters in filenames, so browsers will adjust the suggested name if necessary.
