You (or rather, Dancer, if that's what you're using) provide PSGI with an app handler subroutine. For example:

True! However, I'd be interested in seeing how many people are writing their own Plack::Middleware components. As it's a nice and easy way to replace a lot of work you normally might be forced to write with mod_perl handlers, I would expect that the use of custom Middleware should rise over time as well.

That would be an interesting/useful metric.

I have a question for all you Dancer users. When would you use
Catalyst over Dancer? Does it "scale" better for larger applications,
and if so how/why? I was never able to wrap my head around Catalyst.
But it's been a while and I was a perl beginner back when I tried.
Now Dancer is my go-to framework for any project. Just wondering if I
am missing out on anything.

Thanks,
Naveed

I guess you are really asking all "Dancer users who may have also used
Catalyst." I once tried to install Catalyst, but it insisted on
installing a boatload of crap so I gave up.

Probably never.

I think the better approach might be, is there some specific
functionality that you want that Dancer doesn't provide but Catalyst
does. If yes, it might be worthwhile extending Dancer accordingly. If
not, are both more than one WTDI.

Looking further, I'm seeing various things for doing rewrites of
SCRIPT_NAME for reverse proxies, but not for the rewrite rules of the
form used for the fcgi/cgi deployment.

I'm not sure if this is a good solution or not but plack lets me
define a middleware:

package FixScriptName;
use parent qw(Plack::Middleware);

use strict;

sub call
{
my($self, $env) = @_;
$env->{SCRIPT_NAME} = '';
return $self->app->($env);
}

1;

which I can then enable in config.yml:

plack_middlewares:
-
- +FixScriptName

and uri_for does what I want it to, in this case anyway.

I tried to set up a dancer psgi file to use the Plack Builder DSL to
do configs, but couldn't get it to go right. It seems a little inside
out to define the middleware stack for a dancer app inside the dancer
app configuration. This hack lets me get moving on making my
application do what I want tho.

Hi!

I've read http://advent.perldancer.org/2010/3 and I have a question.

In the blog implementation, described in the article there is so called "flash".
There is a global variable where one stores some message that is
available after redirect:

my $flash;
sub set_flash { $flash = shift }
sub get_flash { my $msg = $flash; $flash = ""; return $msg } )

post '/add' => sub {
# some lines skipped
set_flash('New entry posted!');
redirect '/';
};

I think there can be a problem with this thing: if there are a lot of
requests to the site some user can see the flash message that was done
for some other user.

Am I right?

I can see several ways of doing the same way but in more safe way:
1. redirect to page with parameter that identifies flash message (have
a problem with not pretty urls)
2. store id to flash message in a cookie
3. store flash message in a session

Any other ways?
