****************************************************************
Many Web servers allow for the suppression of the 'server:'HTTP
Response Header in responses.  WebSphere Application Server for
z/OS should provide similar support.
Problem conclusion
A new environment variable, SERVER_TOKEN_OFF, has been added to
WebSphere Application Server for z/OS v4.0.1 that enables the
'server:' HTTP Response Header to be suppressed.
Use the WebSphere for z/OS Administration application to add
this environment variable to the current.env file. You can then
set this variable to "true", to suppress the server header from
the HTTP response. If this variable is set to "false", the
server header will be included in the HTTP response. If this
environment variable is not added to the current.env file, the
server header will continue to be included in the HTTP response.

If you want the server header to continue to be included in the
HTTP response, no action is required after application of the
PTF containing this APAR.

APAR PQ83094 requires a change to documentation:

The following information will be added to "Appendix A.
Environment and JVM properties files" in WebSphere Application
Server V4.0.1 for z/OS and OS/390: Installation and
Customization, GA22-7834-07, and WebSphere Application Server
V4.0.1 for z/OS and OS/390: Assembling J2EE Applications,
SA22-7836-06.

SERVER_TOKEN_OFF= true|false

Determines whether the 'server'.HTTPResponse Header is to be
suppressed. If this variable is set to "true" the server header
from the HTTP response will be suppressed. If this variable is
set to "false", the server header will be included in the HTTP
response. If this environment variable is not added to the
current.env file, the server header will continue to be
included in the HTTP response.

Example:
SERVER_TOKEN_OFF=true
