How to suppress $WSEP header in Websphere Liberty Core 17.0.0.1

I have an application running on the Websphere Liberty Core 17.0.0.1. Whenever it responds with 4xx status code web container adds header named $WSEP to the response. For example:

$WSEP →
Cache-Control →no-cache, no-store, max-age=0, must-revalidate
Content-Language →en-US
Content-Type →text/html;charset=UTF-8
Date →Tue, 30 May 2017 13:21:21 GMT
Expires →0
Pragma →no-cache
Transfer-Encoding →chunked

I tried to add web container property suppressErrorPageODRHeader into my server.xml do suppress this header, however it doesn't work.

<webContainer suppressErrorPageODRHeader="true"/>

How can I configure my web container to suppress this header?

Solution

  • You should use the full webcontainer name "com.ibm.ws.webcontainer.suppresserrorpageodrheader" and that should suppress $WSEP header.

    Some of the original/old WAS properties do not have shortname in Liberty.
