Using Content-Disposition Header

Hi,

Is there any way to use the 'Content-Disposition' header with Catalyst to
prompt the user to download a file?

Using the Apache module, I'd simply set up the header, open the file, and
print the contents to STDOUT.

Under Catalyst doing this, or setting $c->res->body() to the contents causes
the file to get corrupted (because it's treating it as text?)

Any help would be appreciated.

Thanks,
Sam.

Others will no doubt know better, but this from my notes:

Use the 'attachment' keyword on content-disposition to hint to the browser that this file should not be displayed but rather saved:
Content-Disposition: attachment; filename="Culver_OL_2.LAS"

Use the 'name' on the content-type as yet another way (in addition to the above) to suggest what the saved filename should default to:
Content-Type: application/octet-stream; name="Culver_OL_2.LAS"

Of course the actual mime type _should_ be accurate, like "application/pdf", but using "application/octet-stream" is supposed to help the browser decided to save as a file rather than try to display.

Exactly, in Catalyst code this is for example:
$c->res->headers->header( "Content-type" => 'text/csv');
$c->res->headers->header( "Content-Disposition" => 'attachment;
filename=export.csv');
