APAR status

  • Closed as program error.

Error description

  • When using chunked encoding with HTTP compression, DataPower
    might incorrectly read the end of the transaction and be unable
    to process a following transaction, either reading in a request
    or reading in a response to the device.
    

Local fix

  • For requests to DataPower, disable HTTP compression in the HTTP
    Front Side Handler.
    
    For responses to DataPower, disable HTTP compression in the
    Main tab in the Multi-Protocol Gateway or Proxy Settings tab
    in the Web Service Proxy.
    

Problem summary

  • Incoming messages (from either front or backend) having
    "Content-Encoding: gzip" and "Transfer-Encoding: chunked" might
    corrupt subsequent request or response on the same persistent
    connection. All services that handle HTTP traffic are affected.
    

Problem conclusion

Temporary fix
