BinaryWrite and filenames

Hi.
I am trying to implement binary write code, and have it working with
the code shown below (note: this is only sample code - this code would
not be put into production and I am aware of the problems it currently
has). I still have one problem which has me stumped.

Any file sent to the browser this way always takes the name of the
running script. Eg, so I am streaming "test.zip" but when the file save
as dialog pops up, it offers the name of "downloadTest.asp".

Is there a way around this ?
I am guessing I need to add another header, but cant find what to add :(

This is the source:
"downloadTest.asp"
<%

$Response->{ContentType} = "application/pdf";
my $file = "/home/testapp/data/downloads/test.pdf";
open FH, $file;
binmode FH;
$/ = undef;
my $data = <FH>;

$Response->Clear;
$Response->AddHeader('Content-Length',length $data);
$Response->BinaryWrite($data);
$Response->End;
%>

Try calling your script as
<a href="..../downloadTest.asp?file=test.zip">

It should trick your browser.

Thanks for the advice, but unfortunately it did not work for me.
I have found a solution which is to set
"$Response->AddHeader('Content-Disposition',"attachment;
filename=test.zip");"

This works fine in Konquerer, and Mozilla 1.1 on Linux, and on Windows
IE, Opera, but NOT Mozilla 1.2.1.
I am guessing it might be a mozilla bug as mozilla names the
downloadable file to be "test.zip.asp"

Anyone got any thoughts ?
Richard

Sorry, my original post was wrong. But this one is working for me on all
browsers:
<a
href="http://url/download.asp/filename.zip?.asp&file=filename.zip">filename.zip</a>

You shouldn't need to call the script with the filename, and it
might not be desireable or practical. The ContentType I believe has
worked for me. I can't remember off hand, I'd have to check the
details at work. I know Content-Disposition is often required for
emails though as is perfectly legit MIME.

This seems to be a general ASP problem, not just Apache::ASP. There
are plenty of IIS ASP BinaryWrite and filename problems on
groups.google.com (Content-disposition being one solution).

P.S. With PDFs there are additional problems with the Acrobat reader
plug-in. One in particular was the need to set the Content-Length.

Well, my download.asp read and output the file given by the file
parameter, so it was kind of necessary where I used this :-) This is a
copy-paste working example, not how you should do it.

It did not work for me on all browsers, though. Some browsers (I don't
remember which one) just wanted to download script.asp all the time,
that is why the fancy parametering is used in my example.
