how to get server name in microfocus and use the web config

I am trying to get the server name in microfocus asp.net and use the same to invoke the connection string from web config.

 This is what we do in asp.net - is there a analogous syntax in Microfocus - 

 

if (HttpContext.Current.Request != null){
strSvrName = HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString();
}

switch (strSvrName.ToUpper())
{
case "LOCALHOST":
case "XXXDEV.WEB.XXX.COM":
string strDbConn = ConfigurationManager.AppSettings["devconn"];
break;
case "XXXTST.WEB.XXX.COM":
string strDbConn = ConfigurationManager.AppSettings["testconn"];
break;

case "XXXPRE.WEB.XXX.COM":
string strDbConn = ConfigurationManager.AppSettings["prodconn"];
break;
case "XXX.WEB.XXX.COM":
break;

}

 

Thanks
