Problem summary

• ****************************************************************
  * USERS AFFECTED: IBM WebSphere Application Server version     *
  *                 6.1 proxy users.                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: Plugin ESI invalidation requests        *
  *                      could not pass through the proxy        *

  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the plugin is deployed in front of the Websphere proxy
  server, the ESI invalidation requests could not pass through
  the proxy server. The problem is caused by proxy buffering ESI
  request body before forwarding it to the invalidation servlet.
  

Problem conclusion

• To enable proxy handling of incoming ESI invalidation requests,
  3 custom properties need to be defined in the proxy settings
  panel:
  
  Property: http.customFilterChainsTemplate0.filters
       Value: ESI_Invalidator_Filter_Group
  Property: http.customFilterChainsTemplate0.name
       Value: ESI_Invalidator_Template
  Property: http.customFilterChainsTemplate0.uris
       Value: /_DynaCacheEsi
  
  The fix for this APAR is targeted for fix pack 6.1.0.17.
