At the moment (at least in TC 5, which is the only one that returns a 200
Response), this is handled by the Default-Servlet (which ever one is mapped
to '/', which defaults to DefaultServlet) in the ROOT Context.  So, the
current response according to you is still wrong if I have the the 'webdav'
Context installed.

<rfc-quote rfc="2616" section="9.2">
If the Request-URI is an asterisk ("*"), the OPTIONS request is intended to
apply to the server in general rather than to a specific resource. Since a
server's communication options typically depend on the resource, the "*"
request is only useful as a "ping" or "no-op" type of method; it does
nothing beyond allowing the client to test the capabilities of the server.
For example, this can be used to test a proxy for HTTP/1.1 compliance (or la
ck thereof).

I'm starting to lean to putting this into the Connector, rather than sending
it to the Servlet (who can't possibly give a server-wide answer).  Note:
I'm only interested in the case where the Request-URI.equals("*").  All
other cases will go to the Servlet.
