APAR status

  • Closed as program error.

Error description

  • Affected are DataPower MultiProtocol Gateway (MPGW), Web
    Service Proxy (WSP) and Web Application Firewall (WAF) services.
    The services don't preserve HTTP Content-Length header larger
    than 32k if the following conditions are met:
    - HTTP 1.0 on the request side
          (either forced by FSH or by request)
    - Response Type in MPGW/WSP/WAF is set to passthrough
    - Backend does send Content-Length header
    Please be aware of these specific conditions. As other cases
    allow to omit Content-Length header following RFC 2626 Section
    4.4.
    

Local fix

  • Use XML Firewall service.
    

Problem summary

  • Affected might be the customers using the Multi-Protocol
    Gateway, Web Service Proxy or Web Application Firewall with a
    HTTP(S) 1.0 Front Side Handler.
    
    When the Response Type of the service is Pass through, the
    Content-Length HTTP header is preserved from backside to
    frontside only when the original content is less than or equal
    32000 bytes. When bigger, the header is not included.
    

Problem conclusion

Temporary fix
