1.1m5 automatic static file redirects

I have a static Directory routed to "http://someurl"

In 1.1m4 a client could do a GET to either this URL or the URL with a
"/" appended, and the static index.html file would be returned.

I moved up to 1.1m5 over the weekend and my tests indicate a redirect
to the client now occurs for "http://someurl" to the URL with a "/"
appended.

This does not seem like a really big deal, but if most requests are to
the shorter URL, then each will incur a redirect.

Is there a reason for this new behavior?

Thanks
