I've used Richard Lynch's Blog example for forcing the download of an

Is there a way to download multiple files in one go, short of
zipping them
first into a single file?

Concepts / directional shoves appreciated.

I wouldn't think so, Dave, because headers for each file need to
be sent at the request for download, and headers cannot be sent after
the header buffer has ended (when the data buffer is being sent).


I may be showing my ignorance of what can be done... But couldn't you
write a script in PHP (Or some other language) that would link to a
bunch of files and send each one individually to the browser as a
separate file? something like:

<PHP

$filesArray(file1, file2, file3);
foreach($filesArray)
$header ="Blah blah balh"
$header .="More blah blah blah"

Or am I way off base as usual? :)

My original thought was as Daniel suggested, but I had a similar cognitive
storm, Jason, and I gave it a try.

I didn't get any headers already sent error messages, but only the last file
in the array was downloaded.

I didn't think such a thing could be possible because the *browser* is
not expecting it. (I was not aware of anything in http that defined a
method for multiple files in the response the same way you can send
multiple parts in a request or in a multipart mail message. I figured
in any case you would get at most one file (if not an error), and that
that file would contain either A) only the contents of the first or
last file pushed to the client or B) the contents of all the files,
munged together in one chunk.

However, your message prompted me to find this on Google. (It's ASP,
but should be easily converted).

I haven't tried it, so I can't really say if it works, but it's the
only way I could expect it to work.
