Split rtmp url

Lets say I have an rtmp url:

rtmp://site.com/app/video.flv

I connect to rtmp://site.com/app/ and play video.flv.

But what if I had:

rtmp://site.com/app/xxx/video.flv

  1. Is this possible?

  2. Would I connect to rtmp://site.com/app/ or rtmp://site.com/app/xxx/, is there enough info to tell?
