in reply to Content-Disposition... odd behavior in IE

I don't have IE to test with, but based on a Google search the following has a good chance of fixing it. 
#!/usr/bin/perl
use strict;
print "Content-type: application/octet-stream\n";
print "Cache-Control: private\n";
print "Content-disposition: attachment; filename=big-test.csv\n\n";
print "Test,One,Two,Three\n";
exit;

    No dice :(

    The Cache-Control header didn't change a thing. But it does seem to be something to do with the cache. Almost like IE is deleting the file immediately after it creates it.

      Perhaps capitalization matters? 
      #!/usr/bin/perl
use strict;
print "Content-type: application/octet-stream\n";
print "Cache-Control: private\n";
print "Content-Disposition: attachment; filename=big-test.csv\n\n";
print "Test,One,Two,Three\n";
exit;

      Update: And if that doesn't work, perhaps 
      #!/usr/bin/perl
use strict;
print "Pragma: \n";
print "Cache-Control: \n";
print "Content-Disposition: attachment; filename=\"big-test.csv\"\n";
print "Content-type: application/octet-stream\n\n";
print "Test,One,Two,Three\n";
exit;

      (It is frustrating that I can't test these suggestions, but I don't have IE to test with and it is a browser issue.)

        Perhaps capitalization matters?

        Capitalisation is not suppose to matter for HTTP header names (but you never know), and you already rely on the case-insensitivity (by using "Content-type" instead of "Content-Type").

        Still no luck.

        After playing around with the cache idea in mind, I have noticed if the helper app is open the file opens sometimes (worked with Excel, but not Acrobat).

        This is confirmed with looking for files created in the cache folder.

        IE is either deleting or not creating the file in the cache.
