Finding Files with VHost

[Chris Sphinx]

Hey guys, I've got a quick question. I'm using a vhost and _rewrite to 
serve up a webpage and I'm trying to get the page to include a separate 
javascript file.

http://184.75.155.16.xip.io:5984
Script is running fine, but I'm using a rewrite to point it correctly:

[
    {
       "from": "",
       "to": "index.html"
    },
    {
        "from": "hello.js",
        "to": "script/hello.js"
    }
]

I'm wondering if there is a better way to do this? Or do I need a 
rewrite for every file I'm going to be using on my page? How do I set 
the src path correctly if I'm using vhost and _rewrite?
