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
Fix is available in 6.0.0.12, 6.0.1.8, 7.0.0.5 and 7.1.0.3. For a list of the latest fix packs available, please see: http://www-01.ibm.com/support/docview.wss?uid=swg21237631
