IT22481: CHUNKED ENCODING WITH HTTP COMPRESSION MIGHT CAUSE THE NEXT HTTP MESSAGE TO BE READ INCORRECTLY
Fixes are available
Closed as program error.
When chunked encoding and HTTP compression are enabled, some requests might fail with the following error: [0x80e00629][mpgw][error] mpgw (MPG_Tester): tid(1587703)[126.96.36.199] gtid(1587703): The header (0) is wrong when connecting to URL 'https://me.ibm.com/ This occurs with persistent connections where packet fragmenting of a gzip+chunked HTTP message might leave stray bytes and corrupts the next message.
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.
Affected are all customers using HTTP (gzip) compression with chunked encoding on either side of their DataPower services. In some TCP packet fragmentation patterns, the reading side of such data stream can get satisfied sooner than the actual end of the chunk-encoded payload, which will then corrupt the TCP stream for the following transfer through the same persistent connection.
Fix is available in 188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124 and 126.96.36.199. For a list of the latest fix packs available, please see: http://www-01.ibm.com/support/docview.wss?uid=swg21237631
