We have 3 seperate report applications each pulling from its own cube and
database deployed on Report Server. We would like to have a directory for
each application (so we can restrict by IP range). Can we set up a virtual
directory for each report application deployed on report server? Currently
all requests forward to the report server virtual directory, so we can
restrict by ip range on the initial request via forward from another virtual
dir, but since afterwards they all sit in the report server virtual
directory, we can no longer restrict them from hopping into the other
applications (given they know the url/parameters)

any ideas?
