Perl Question

uri_for includes port number on redirects

I'm attempting to implement a Catalyst application using nginx as a frontend web proxy for static files, and using Starman for my backend webserver. (I could use Apache & FastCGI and it works just fine, but I'd really like to get the whole PSGI / Plack and Starman thing ironed out)

Starman starts up okay and can handle my requests just fine on

http://localhost:5000
. When I fire up nginx to use as my front-end proxy, my urls become ugly and mangle with the port number (5000) whenever or wherever I use the
$c->uri_for
method.

Example :


$c->uri_for("/login")
becomes
http://myapp.example.com:5000/login
rather than
http://myapp.example.com/login


I have some logs being created so I can see what
X-Forwarded-Host
and
X-Forwarded-For
are set as. For normal requests, there are values set (coming from nginx), but whenever the
$c->uri_for
method is used, those values do not exist.

Has anyone else had this problem?

Am I missing something else in my configuration of either nginx or my Catalyst conf?

Thanks!

nginx config :


server {
listen 80;
server_name myapp.example.com;

location /static {
root /data/users/MyApp/root;
expires 30d;
}

location / {
proxy_set_header Host $host;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_pass http://localhost:5000/;
}
}


Event though this will be ran on the same physical server, in MyApp config I have set :


MyApp->config(using_frontend_proxy => 1)


Versions :


Catalyst : 5.80024
nginx : 0.7.67
Plack : 0.9942
Starman : 0.2006

My problem was in my myapp.psgi file.

from Catalyst::Engine::PSGI and look at Plack::Middleware::ReverseProxy:

...
use Plack::Builder;
use MyApp;

MyApp->setup_engine('PSGI');
my $app = sub { MyApp->run(@_) };

builder {
 enable_if { $_[0]->{REMOTE_ADDR} eq '127.0.0.1' } 
        "Plack::Middleware::ReverseProxy";
 $app;
};
