[Dancer-users] CGI/FCGI deployment & uri_for

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);


which I can then enable in config.yml:

     - +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.
