Local fix
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.
