Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: For an inbound request, the server      *
  *                      invokes the same filter multiple        *
  *                      times.                                  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When an inbound request URI maps to multiple URL filter
  mappings the filter chain will be updated with the same filter
  multiple times. This will result in the filter being invoked
  multiple times for the same URI.
  

Problem conclusion

• The WebContainer code has been updated and a filter will not
  be added if it is already present in the chain.
  
  To get this new behavior the following new WebContainer custom
  property needs to be set:
  
  com.ibm.ws.webcontainer.denyDuplicateFilterinChain= true
  (default =false)
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.0.0.8, and 8.5.5.1.  Please refer to the
