* PROBLEM DESCRIPTION: Session data might get lost if a        *

****************************************************************
If a session ID is reused, the cache ID retrieved must also be
reused.  Otherwise, there will be a cacheID mismatch.
Problem conclusion
Support was modified to set cache ID according to the cache ID
retrieved from the cookie/browser.
