Re^2: Changing the content type

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.

To add to Fletch's (rather unnecessarily vociferous) correction, the right way to do it is to pass both arguments to `header` at the same time. `print $q->header(-type => 'text/xml', -attachment => 'filename.xml');` [download] If you're using a framework like CGI::Application, there are utility methods for keeping track of multiple headers and outputting them exactly once, so you don't have to keep track of lots of print statements and won't accidentally print two sets of headers.
