You need to send valid HTTP headers before the output of your script. The
best way to do this is by using the CGI.pm module and calling the 'header'
method. You can manually set the header yourself by doing a print
"Content-type:foo/bar", but you're better off using CGI.pm, as it will
eliminate any potential mistakes you might make in setting the headers
yourself
e.g.,
#!/usr/bin/perl -w
use CGI;
use strict;
my $q = new CGI;
print $q->header;
print "Hello World!\n";
Also remember to ALWAYS use strict and -w, no matter how trivial the script.
