I'm sorry, I mistyped. If / -> /jq I'd expect that a request for
/index.html would go to /jq/index.html but that a request for / would
go to /jq

If you were to request /jq then you'd get /jq/jq of course.

What if you watch the HTTP conversation with the server using fiddler,
firebug, your browsers built-in dev tools, etc.? Are you seeing any
redirects issued by the server?
