Symptom:
URL rewrite feature isn't including the entire query string in the new url.  Instead,  the regex match stops at first ampersand (&) in query string resulting in an incomplete rewrite.

Conditions:
URL rewrite action-list.  For example,
A url of '/foo/bar?one=1&two=2 with an action list of
'url  rewrite  "/foo/(.*)" replace "/%1' should be rewritten
as '/bar?one=1&two=2' but instead is rewritten as
/bar?one=1 excluding the '&two=2' section of the original url.
