Re[3]: [cgiapp] Nested CGI::App modules (C::A with Fast CGI)

[Aleksey Serba <suppressed>]

    Hello Arkady!

Thank you for your response!

AG> I share your approach 100%.  I think, you cannot create a new CGI::App
AG> instance outside the Fast CGI loop, because you will run into "session
AG> collision" problems.
Perhaps, it would be possible if
i can create CGI::Application instance without CGI compatible object
and specify it later
--------------------------------
    my $app = Pages::Admin::News->new(
        PARAMS => {
                dbh         => $dbh,
        },
        QUERY  => $query
    );
    while( my $query = new CGI::Fast ) {
        $app->set_query($query);
    }
--------------------------------

AG> With Fast CGI it is desirable to use a single DBI

Exactly!

AG> Once you brought up the issue of using CGI::App with Fast CGI, I would

AG> How does HTML::Template caching work with Fast CGI + CGI::App?
I don't have enough experience in CGI::App :(
I'm using FastCGI + HTML::Template for a long time and suppose what
caching works fine in that environment.

AG> I fear that each time I create a CGI::App instance inside my Fast::CGI loop and
AG> use load_tmpl() inside my CGI::App class, the template files have to be
AG> accessed from the hard drive.
I think no. Of course if you using caching options (cache => 1).
Let's see:
1. load_tmpl:
---------
...
require HTML::Template;
...
---------

2. HTML::Template
---------
use vars qw( %CACHE );
---------

-Therefore, recurring 'require' does not clear package variable %CACHE.

-You may check the time H::T template parsed the first and second
times. (Time::HiRes)

-If you still worry, then instead of memory cache you may use shared cache
(IPC)


AG> In that case, it would make sense to
AG> initialize HTML::Template objects outside the Fast CGI loop too.
I don't see any reason.

Thanks.
