IE is broken

IE does a redirect to something that looks like a regular expression path.

For example, trying to load the demo page in IE redirects from here:
http://codemix.github.io/url-route/components/url-route/demo.html

to here:
http://codemix.github.io/%5E[%20/t/r/n/f]+%7C[%20/t/r/n/f]+$/g

Reproduce the redirect from the demo page at http://codemix.github.io/url-route/components/url-route/demo.html in IE, then inspect the URL routing behavior that produces the encoded regular-expression path. Done means the demo page loads in IE without redirecting to that malformed URL.
