[Catalyst] Reverse Proxy setup, base address and placing a CatApp on a subdir

[Pedro Melo]

Hi,

I've have a solution for a problem I have and I wonder if there is a  
better way.

I have an existing site, and I want to add a Catalyst-based app in a  
subdirectory, for example /app.

The setup I've been trying is this:

1. setup a reverse proxy in the main site. With apache, something  
like this works:

<IfModule mod_proxy.c>
     ProxyRequests Off

     ProxyPass /app http://127.0.0.1:3000/
     ProxyPassReverse /app http://127.0.0.1:3000/
</IfModule>

(i'm testing with the builtin server, production would use other  
setup, of course).


2. right now, the setup works, but redirects (for example) fail  
miserably because a redirect inside Cat to /something will go to  
http://main.site/something, instead of http://main.site/app/something.

3. I've looked at the header's sent by apache and I could not find  
anything that would tell me that the reverse proxy is re-proxyng /app  
and not /, so I used this in my App::C::Root:

sub auto : Private {
   my ($self, $c) = @_;

   my $uri = $c->req->base;
   $uri->path('/app');
   $c->req->base($uri);
}


This works, or so far in my tests, seems to work. I could also move  
the "/app" bit to the configuration file, but I don't see a way out  
of messing with $c->req->base in my code.

Correct? Or am I missing something terribly obvious?

Best regards,
