IT19473: HTTP CLIENT IP LABEL DOES NOT WORK

APAR status

  • Closed as program error.

Error description

  • The HTTP Client IP Label does not work as described.
    
    It should allow you to enter the name of an HTTP Header (e.g
    X-Forwarded-For) to determine the IP address of the requesting
    client, which would then be used for monitoring and logging.
    
    Instead, the specified HTTP Header is not used for monitoring
    and logging.
    
    This will impact X-Client-IP header.
    

Local fix

Problem summary

  • Affected are all customers using the http-client-ip-label
    setting present in most of DataPower services. This setting is
    by default set to "X-Client-IP".
    The functionality behind this feature lacked the part where the
    original client IP present in the "X-Client-IP" (or other
    custom) header should appear in the system logs as the current
    transaction client IP.
    
    This fix also introduces a new "network" target "info" priority
    message to mark the moment the logged client IP changes.
    
    For releases up to and including 7.5.2.x the message is:
    > Message 0 is specific to APAR IT19473: <current-client-ip>
    <new-client-ip> <http-header-name>
    
    Future releases will display the same message as more readable:
    > Client IP <current-client-ip> is now tracked as
    <new-client-ip> due to its presence in the "<http-header-name>"
    HTTP header.
    

Problem conclusion
