> According to the discussion about security checklist on dev list I started to 
> check the security features of the existing HttpServer2 and found that by 
> default the XFrame option headers are disabled. This patch enables it by 
> default for SCM/KSM server similar to the Namenode/Datanode webui. 
> (Note: Even if the only form on the SCM/KSM ui-s is the standard LogLevel 
> form, I think it's a good practice to enable it by default.)
> Test:
> Without the patch (clean build, SCM ui):
> {code}
>  curl -v localhost:9876/jmx -o /dev/null
