NAME

CGI::Application::Plugin::TT::LastModified - Set "Last-Modified" header based on TT template

SYNOPSIS

  # when you want to set the "Last-Modified" header manually
    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.html', \%params );
        $self->tt_set_last_modified_header();
        return $html;
    }

  # when you want the "Last-Modified" header set automatically
    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.html', \%params );
    }

DESCRIPTION

CGI::Application::Plugin::TT::LastModified adds support to CGI::Application for setting a "Last-Modified" header based on the most recent modification time of any of the components of a template that was processed with TT.

Normally you'll want to call it manually, on as "as needed" basis; if you're processing templates with TT you're most likely dealing with dynamic content (in which case you probably don't even want a "Last-Modified" header). The odd time you'll want to set a "Last-Modified" header, though, this plugin helps make that easier.

If you have a desire to have the "Last-Modified" header set automatically for you, though, CGI::Application::Plugin::TT::LastModified does have an :auto import tag which auto-registers "tt_set_last_modified_header()" as a "tt_post_process" hook for you. If you've got an app that just processes static TT pages and generates output, this'll be useful for you.

METHODS

import()

Custom import routine, which allows for tt_set_last_modified_header() to be auto-added in as a TT post process hook.

tt_last_modified()

Returns the most recent modification time for any component of the most recently processed template (via tt_process()). Time is returned back to the caller as "the number of seconds since the epoch".

tt_set_last_modified_header()

Sets a "Last-Modified" header in the HTTP response, equivalent to the last modification time of the template components as returned by tt_last_modified().
