APAR status

  • Closed as program error.

regarding the HTTP Strict Transport Security header not be
added in these scenarios.

  • N/A

Problem summary

  • ****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere                  *
*                  Application Server version 8.5.5 and 9.0    *
****************************************************************
* PROBLEM DESCRIPTION: HTTP Strict-Transport-Security (HSTS)   *
*                      header is missing for a 404 response.   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When a secured request is made to a non-existent application
(i.e non-existent context root), a 404 response is returned
without the HSTS header even when one has been configured via
the WebContainer custom property
com.ibm.ws.webcontainer.addStrictTransportSecurityHeader

Problem conclusion

  • The WebContainer code was changed to include the HSTS header
in the response for a secured request to a non-existent
application.  The current WebContainer custom property is
required for this to work:

com.ibm.ws.webcontainer.addStrictTransportSecurityHeader

The fix for this APAR is targeted for inclusion in fix pack
8.5.5.20 and 9.0.5.8.
