HPCC-30080 Not access restricted resources for Unrestricted call

A user may use several URL parameters (ex. wsdl) to retrieve Unrestricted resources (the xsd files, wsdl files, and sample files in Open sources). The code is added to block the access to other resources. Signed-off-by: wangkx <[email protected]>
