Facebook Unity3D file

Hey everyone,

I've been trying to figure out a way to be able to make new web builds in Unity, host it up on a server, and not have to change the URL link for Facebooks Unity integration.

I've got a node server running that has '/.unity3d' as a route, and I've placed that URL in Facebooks app settings. I see it hit the endpoint, but I'm not sure how to return the unity3d file properly.

Any idea if this is even possible?

EDIT: Figured it out. response.redirect(url); works just fine.
