Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * Worklight/MobileFirst Platform customers using DataPower as  *
  * a proxy                                                      *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * A recent DataPower patch has caused some empty network       *
  * responses to contain the Content-Encoding header "gzip".     *
  * This causes network requests going through DataPower to      *
  * fail, since checking gzip encoding requires looking at the   *
  * first 2 bytes (which in this case, does not exist).          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * -                                                            *
