With the HTTP-headers variable we have to define in our Perl script:
use Nes; my $nes = Nes::Singleton->new('template.nhtml'); my $nes_tags = {}; $nes_tags->{'HTTP-headers'} = "Content-type: text/html\n\n"; $nes->out(%$nes_tags);
We can control the headers of the HTML output.
When Nes verifies that HTTP-headers has value, prints its content and not the headers by default. Should be included immediately after the NES Tag:
{: NES 1.0 ('file.pl') :} {: $ HTTP-headers :}
If you define HTTP-headers and then not included with {: $ HTTP-headers :} we get an error.
template.nhtml:
{: NES 1.0 ('file.pl') :} {: $ HTTP-headers :} <html> <head> ...file.pl:
use Nes; my = Nes::Singleton:Singleton->new('template.nhtml'); my $nes_tags = {}; $nes_tags->{'HTTP-headers'} = "Cache-control: max-age=0\n"; $nes_tags->{'HTTP-headers'} .= "Cache-control: no-cache\n"; $nes_tags->{'HTTP-headers'} .= "Content-type: text/html\n\n"; $nes->out(%$nes_tags);
