can't enable http protocol on connection server

Hello,

according to view-61-scenarios-ssl-certificates.pdf, I added a locked.properties file under C:\Program Files\VMware\VMware View\Server\sslgateway\conf

serverProtocol=http

serverPortNonSSL=8670

serverHostNonSSL=0.0.0.0

and then restarted the service even the connection server, but got nothing changed.

netstat -na output:
