giving a filename hint to the browser?

[Mark Harrison <mh...@pixar.com>]

I have a module that is serving out images in various formats
and resolution.  Our canonical format is:

/operation/image/resolution

for example, to get a jpeg thumbnail of foo.tif 256 pixels:

http://myserver/thumb/foo.tif/256-wide-jpg

This is all working well now and fits in with how other parts
of our system think about images, but I'm curious if there is a
way to hint to the browser a "save-as" filename.  Currently
if you save the file (or drag the image to the desktop),
the default name will be "256-wide-jpg.jpg", and it might be
nice to save it as "foo.tif.thumbnail.jpg" or some such.

Many TIA!
Mark

Ah, that's perfect.  Firefox honors it on "Save As...",
and Safari honors it on both "Save As..." and when dragging
the image to another app or the Finder.

Thanks a bunch!

For future googles:

     snprintf(disposition, sizeof(disposition), "inline; filename=%s", hint);
     apr_table_add(r->headers_out, "Content-disposition", disposition);

Google Content-Disposition.  This is techincally a
MAIL header, not an HTTP header, I think, but the
major browsers seem to pay some attention to it,
at least some times.
