Is there any way to specify a suggested filename when using data: URI?

Question

If for example you follow the link:

data:application/octet-stream;base64,SGVsbG8=

The browser will prompt you to download a file consisting of the data held as base64 in the link itself. Is there any way of suggesting a default file-name for the browser to use? If not, is there a javascript solution?

I'm referring to HTML hyperlinks.

Answer 1

According to RFC 2397, no, there isn't.

Nor does there appear to be any attribute of the <a> element that you can use either.

Answer 2

I was unsure of what you meant by 'the link' as I don't see one. But if you add this Header to the response:

Content-Disposition: attachment; filename=somefilenameijustcameupwith.doc;

In C# this is done with: Response.AddHeader("Content-Disposition", "attachment; filename=" + filename);
