I’m trying to use a load balancer to redirect based on path to different apps. For example, I’d like  
`example.com/app1` to forward to a stack or service called app1. The problem is the request path is being passed along with the forwarding request. So app1 hosted at `192.168.0.5` gets a request of `192.168.0.5/app1`. From what I understand of HAProxy, I could do this in the config with `reqrep`

```
backend app1_backend
   reqrep ^([^\ :]*)\ /app1/(.*) \1\ /\2
   server app1 rancher_private_IP:80

```

Is there a different way to do this in Rancher?

There is not currently a way to do this. We’re considering a way to let you add custom haproxy config in [#1871](https://github.com/rancher/rancher/issues/1871).

What you describe can’t be the default configuration because it won’t work right if the application returns any absolute or root-relative links/CSS includes/other things, which is pretty common. So alternately you configure the application to know that it is running from the base url `/app1` instead of `/`.

Ah that makes sense. I suppose the best way to do it then would be to forward based on subdomain (`app1.example.com`) if possible.

Yup, and you can do hostname-based routing today.

</div>

and is there a way to make a global match based on subdomain?  
ie:

[chat.domain.com:80](http://chat.domain.com:80) =\> container \>\> chat port 80  
[branch1.domain.com:80](http://branch1.domain.com:80) =\> container \>\> deployed branch1 port 80

so instead of having to manually specify the subdomain to container mapping, is it possible to setup a global subdomain match to container name, and if such container exists and has this specific port open then serve content from it

Even better - there’s a great project on github by jwilder/nginx-proxy - it basically looks for any container that has  
VIRTUAL\_HOST=[www.domain.com](http://www.domain.com) and optionally VIRTUAL\_PORT=3333  
if any container on the network exists with these environment varaibles - then it auto-magically updated nginx.conf to create virtual hosts with SSL support.  
Is it possible to achieve similar behavior through Rancher or can this functionality be added?

Thank you

@virtuman Currently, this functionality doesn’t exist. You can file an enhancement request in Github for your use case.
