Re: Sending a file through STDOUT using HTTP

The correct way to set the content type and disposition is (untested)

print "Content-type: archive/zip\n" .
          "Content-Disposition: attachment; filename=$filename\n\n";
binmode STDOUT;
$zip->writeToFileHandle( \*STDOUT, 0 );
[download]

There's a few points here:

The correct way to set the content-disposition is with the filename= part but without the quotes around the filename (I think).
With your current code you are trying to append the result of writeToFileHandle to your string. I think you mean ";" instead of "."
writeToFileHandle expects a filehandle reference, not a string corresponding to the name of a filehandle.
You should set binmode on a filehandle before writing binary data to it.

Give that a shot.

Good points! But, I did have to use the quotes around the file name in the past to handle files with spaces in their names. Ted Young `($$<<$$=>$$<=>$$<=$$>>$$) always returns 1. :-)`	[reply] [d/l]

Excellent points and I definitely appreciate the info. I now have: `$zip->addTree( $path, '' ); print "Content-type: application/zip\n" . "Content-Disposition: attachment;filename=\"$filename\"\n\n"; binmode STDOUT; $zip->writeToFileHandle( \*STDOUT, 0 );` [download] Unfortunately the browser is still seeing it as a "httpd/unix-directory" and not getting a filename. I tried both with and without quotes on the filename. Any other ideas? Stupid MIME types...	[reply] [d/l]

I did a quick search on Google and it looks like the "httpd/unix-directory" think might be an Apache configuration issue. Are you sure your CGI code is actually getting executed? Maybe add something like `print STDERR "My CGI called here"` and see if that message shows up in your Apache error log.	[reply] [d/l]

Well I'm pretty sure it gets called because the file does actually send. I printed to STDERR anyway and it showed up in the error_log correctly. Hmmm.	[reply]
