APAR status

• Closed as program error.

Error description

• Messages that contain the HTTP header Content-Encoding=gzip are
  unzipped when RIT receives them.
  When they are sent on to the real system by a stub in
  pass-through mode, they are not re-compressed.
  
  The HTTP header is preserved so it has the header property
  "gzip" set but with uncompressed content.
  The target system cannot decode the message.

  * USERS AFFECTED:                                              *

  * PROBLEM DESCRIPTION:                                         *
  * When using the sift and pass-through feature with the HTTP   *
  * proxy, messages  that contained the HTTP header              *
  * "Content-Encoding=gzip" were not understood by the live      *
  * system when they were 'passed through' to it because the     *
  * contents of the message had already been uncompressed.       *
  ****************************************************************
  * RECOMMENDATION:                                              *

Problem conclusion

• In version 8.7.0 of Rational Integration Tester this problem was
  resolved and the message passed-through to the live system now
  contains compressed content in line with the header setting.
