To clarify, I meant to say, "I only occassionally write handlers". :)

Thanks Jim, I'm going to give that a try and see if I can get it to work.

Yes, that's what I have in mind. I only occassionally write headers.
But I envision something similar to what you've got below:
$redirect = ... ; ## URL to the spreadsheet
$r->content_type('text/html') ;
$r->headers_out->set( Location => $redirect ) ;
$r->send_http_header ;
$r->print( $content->output ) ;
return Apache2::Const::REDIRECT ;
Originally, I wondered about using a "multipart/mixed" response type.
I've never heard that any browser supports such a thing. Although that
seems like a more elegant solution.

I'm not sure what I follow you, something like this?
$r->content_type('text/html');
print $content->output;
$r->headers_out->set(Location => $redirect); return
Apache2::Const::REDIRECT;
And the $redirect URL would then do the sending of the file itself?
Thanks!

I believe the following will work (never tried it though):
The request should return a 'text/html' type document that displays
the instructions. But the response should be a redirect to a URL that
returns the spreadsheet instead of a 200 OK. I believe that the body
of the original response will be displayed until the redirect succeeds.
In the old days, we performed this trick by using meta tag equivalents
of the response headers. And I expect browsers will respond to actual
HTTP headers the same way. I say "the old days" because for last 18
years, I've relied on javascript. But there may be reasons for not
wanting a different type solution.

Hi,
I'm trying to have a form submission package up the results in a xls
file and then start the download for the user as well as present a
page where they can click on the file if the download has not already
automatically started.
I can do each separately but not both together, I have something like
this:
... Make up our xls file download and put it in $output
$r->content_type('application/xls');
$r->err_headers_out->add('Content-Disposition' => 'attachment;
filename="'
.
$download_name . '"');
$r->print($output);
$content->param('set some html template vars....');
$r->content_type('text/html');
print $content->output;
When I due the above, then I get prompted for the download but that
is it, I never get the page. Even if I reverse the order and try to
do the page
first:
$r->content_type('text/html');
print $content->output;
$r->content_type('application/xls');
$r->err_headers_out->add('Content-Disposition' => 'attachment;
filename="'
.
$download_name . '"');
$r->print($output);
$content->param('set some html template vars....');
That still doesn't work. Probably not a mod_perl specific question
but I'm hoping someone can shed some light
TIA!
