Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server web        *
    *                  server plugin users with websockets         *
    ****************************************************************
    * PROBLEM DESCRIPTION: Client address for websockets not       *
    *                      provided to WebSphere.                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The web server plugin adds headers to requests forwarded to
    WebSphere that provide client details such as client address.
    These headers are referred to as plug-ins 'special headers'
    and have header names starting with $WS.  Plug-in was not
    setting these headers for websocket requests.
    Users can experience errors such as 'HTTP 403 - Resource
    Forbidden' when a request is received and the request does not
    provide the client information.
    

Problem conclusion

  • Plug-in was corrected to set the special headers for
    websocket requests. Note-If a response for 403/Forbidden is
    received for websocket requests after applying this code
    change, please ensure trustedSenstiveHeaderOrigin is set
    if necessary as documented in apar PH07036.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.19 and 9.0.5.6. For more information, see 'Recommended
