Is it possible to remove the 'Server' header from the response of a mockservice?

In a mockservice for a soap request I return a response.

Default it returns the following 5 header values

Transfer-Encoding chunked
#status# HTTP/1.1 200 OK
Content-Encoding gzip
Content-Type text/xml; charset=utf-8
Server Jetty(6.1.26)

I do not want to expose the Server value. Is this possible?
