FAQ Topic - How do I prompt a "Save As" dialog for an
accepted mime type?
-----------------------------------------------------------------------

It is not possible with client-side javascript.

Some browsers accept the Content-Disposition header, but this
must be added by the server. Taking the form:-
` Content-Disposition: attachment; filename=filename.ext `

I truly wish that this topic was updated from our arguments from last
time...

Last time it came up, there was no discussion. The time before that, I see:
http://groups.google.com/group/comp.lang.javascript/browse_thread/thread/7414cdc6ca1a0005

- is that what you meant?

Therein, the demo page:
http://thenewobjective.com/temp/save.html

Running that demo in IE7, the image is not displayed. Clicking "prompt
save" results in a javascript error: "The data area passed to a system
call is too small."

I recall another discussion where there was mention of a way to get a
similar effect from IE, however nobody wrote a cross browser solution.

This seems to work on all common browsers minus Chrome (where I can't
tell if this is a bug or intentional behavior).

Regardless, the claim that "It is not possible with client-side
javascript." is inaccurate and should be changed to mention the
approaches used through base64 and document.execCommand("SaveAs"...)

The details on what warrants an appropriate example should be separate
debate I think.
