Added check for excessive .. entries which would go out of domain. This addresses possible problems with too many .. entries i.e. if the repo root is http://www.xample.org/repo/proj1 then ^/../proj2 is fine as is ^/../../repo2/p1 but ^/../../../www./Local is not as it doesn't make sense to have relative references that go to a different site.
