DistributedCache localizes only once per cache URI

Details

    Description

      As part of the file localization the distributed cache localizer creates a copy of the file in the corresponding user's private directory. The localization in DistributedCache assumes the key as the URI of the cachefile and if it already exists in the map, the localization is not done again. This means that another user cannot access the same distributed cache file. We should change the key to include the username so that localization is done for every user.
