Apache2::HttpEquiv version 1.00, released January 4, 2014
This module provides a PerlFixupHandler for mod_perl 2 that turns
<meta http-equiv="Header-Name" content="Header Value"> into an actual
HTTP header. It also looks for <meta charset="..."> and uses it to
set the Content-Type.
INSTALLATION
To install this module, run the following commands:
perl Makefile.PL
make
lib/Apache2/HttpEquiv.pm view on Meta::CPAN
my ($p, $token, $header) = HTML::PullParser->new(
file => $file,
start => 'tag, attr',
end => 'tag',
);
my $content_type;
while ($token = $p->get_token) {
if ($token->[0] eq 'meta') {
if ($header = $token->[1]{'charset'} and not defined $content_type) {
$content_type = "text/html; charset=$header";
} # end if <meta charset=...>
elsif ($header = $token->[1]{'http-equiv'}) {
if ($header eq 'Content-Type' and not defined $content_type) {
$content_type = $token->[1]{content};
# text/xhtml is not a valid content type:
$content_type =~ s!^text/xhtml(?=\s|;|\z)!text/html!i;
} else {
$r->headers_out->set($header => $token->[1]{content});
}
} # end elsif <meta http-equiv=...>
} # end if <meta> tag

=head1 DESCRIPTION
Apache2::HttpEquiv provides a PerlFixupHandler for mod_perl 2 that turns
C<< <meta http-equiv="Header-Name" content="Header Value"> >> into an actual
HTTP header. It also looks for C<< <meta charset="..."> >> and uses it to
set the Content-Type to C<text/html; charset=...>.
If the file claims its Content-Type is 'text/xhtml', the Content-Type
is set to 'text/html' instead. 'text/xhtml' is not a valid
Content-Type, and any file that claims it is probably too broken to
parse as 'application/xhtml+xml'.
This works only for static HTML files (that Apache has identified as
'text/html'). If you're generating dynamic content, you should be
generating the appropriate Content-Type and other headers at the same
time.
