  ****************************************************************
  In SSL tunneling (forward proxy secure request), encrypted
  data is passed through the proxy server unaltered. Because the
  proxy server does not unencrypt the data, functions that
  require the proxy server to read requests or document headers
  are not supported in SSL tunneling. Also, tunneled requests
  are not cached.
  Before the fix, if Range header is set to "0-", Caching
  proxy will try to read the whole request. In this case this is
  not allowed and the request will fail.
  As part of the fix, we have disabled the caching for this
  type of request.This will make sure the request will be
  fulfiled without caching.
  

Problem conclusion

• We have disabled the caching for forward proxy secure
  requests. This will make sure the request will be
  fulfiled without caching.
  
  The fix for this APAR is currently targeted for inclusion in
  fixpack 8.5.5.8, 8.0.0.12 and 7.0.0.16
