Changing the content type

[carterniall]

I have a perl script which can print either XML or KMl depending on teh choice of the user. When teh script is run through a browser the user is given the choice of what to do with the file.

I was wondering if there would be a method of allowing them to download and save it as a .XML or .KML extension instead of a .PL extension. I want them to only see it as XML or KML as opposed to a perl script. Any clues as I am coming up stumps.

I have tried changing the content type to: "Content-type: application/vnd.google-earth.kml+xml\n\n"; which was good until they new version of Google Earth stopped that. This method did not help my problem of offering an XML version (.xml) to download though.

Any clues? Sorry if it's a bit vaige but would be more than happy to elaborate...

To set the filename of a downloaded file, add a content-disposition header with a filename attribute. For example

content-disposition: attachment; filename=foo.kml

Many thanks, adding the content-disposition worked a charm

I had a bt of a thick moment as you have to remove the


print "Content-type: application/vnd.google-earth.kml+xml\n\n";

line for the content disposition to work.

Many thanks monks

Not sure if this is what you are looking for, but I use:

print $q->header(-type=>'text/xml');
print $q->header(-attachment=>'filename.xml');

where $q is a CGI object, to make the browser see a file filename.xml of type text/xml when opening my cgi script.

FAIL. That prints two sets of headers.

$ perl -MCGI -e 'my $q = CGI->new(); print $q->header(-type=>"text/xml
+"); print $q->header(-attachment=>"filename.xml");'
Content-Type: text/xml; charset=ISO-8859-1

Content-Disposition: attachment; filename="filename.xml"
Content-Type: text/html; charset=ISO-8859-1

Thank you for the correction. I'll check tomorrow when I'm at office if (a) the above code is really the one I use and (b) if our script shows the same problem!

It is absolutely possible that we have put in production a program that duplicates the content-type and that Firefox accepts it without a warning using the first and discarding the second one.
