Subject: [PATCH] In a subresource the parameter value will be an empty string.

The documentation explains:
when a request targets a subresource, the corresponding query parameter value will be an empty string ("").

Example:
"http://s3.amazonaws.com/examplebucket?acl"

The CanonicalQueryString in this case is as follows:

UriEncode("acl") + "=" + ""
