I use CGI::Application::Plugin::TT to process TT templates regularly, and
although the vast majority of them contain dynamic content, every now and
then I've got parts of sites that are just static files that get served up
via TT (e.g. online help).
Was thinking...
What about a CAP::TT::LastModified module that helped make it easier to set
a "Last-Modified" header in the response? For my purposes I know that the
underlying contents are basically static, and I'd like to set the L-M HTTP
header to help encourage proxies/caches to cache the page.
I was thinking about an interface along the lines of:
tt_last_modified()
- returns the most recent mtime of any -component- of the most recently
processed template
tt_set_last_modified_header()
- using the mtime from "tt_last_modified()" above, set the L-M HTTP header
By default, these two methods would be exported by default, and you'd be
responsible for calling "tt_set_last_modified_header()" yourself.
By using an ":auto" import, though, the module would set itself up
automatically as a "tt_post_process" hook.
General usage would be along the lines of:
use base qw(CGI::Application);
use CGI::Application::Plugin::TT;
use CGI::Application::Plugin::TT::LastModified;
sub my_runmode {
my $self = shift;
my %params = (
...
);
my $html = $self->tt_process( 'template.tpl', \%params );
$self->tt_set_last_modified_header();
return $html;
}
Or, if you knew that you -always- wanted to set the L-M header, you could do
it like:
use base qw(CGI::Application);
use CGI::Application::Plugin::TT;
use CGI::Application::Plugin::TT::LastModified qw(:auto);
sub my_runmode {
my $self = shift;
my %params = (
...
);
return $self->tt_process( 'template.tpl', \%params );
}
Thoughts? Feedback?
