Hi All,
Facing strange problem in our production environment that is redirecting the url is not working if the domain is not having www in the url.

here is the example:

we have one index.html file having the switch function for redirecting the curHost to specific action class and what action class will do is getting the domain(current host) and ip address of user and then read the properties file for getting the target url based curhost.ipaddress.

here the problem is ,if we enter http://chevroletarabia.com it is not working and if we enter like http://www.chevroletarabia.com then it is working fine.

what could be the problem can any one help me on this.

sample of index.html,propertiesfile:

IP REDIRECTION Action:
code snippet of perform method:

String domain=request.getParameter("domain");
  
       if(domain==null||domain.equals(""))
          throw new FusionException("Domain is Null or empty");
   logDebug(this,"fusionPerform","Domain: "+ domain);  
       setLOCALE(request);
       String curHost=request.getParameter("curHost");
   if(curHost==null||curHost.equals(""))
  throw new FusionException("curHost is Null or empty");
   logDebug(this,"fusionPerform","curHost: " + curHost);
       printHeaders(request);
       
       String wlproxyclientIPheader = request.getHeader("WL-Proxy-Client-IP");
       String proxyclientIPheader = request.getHeader("Proxy-Client-IP");
       String clientIPrequest = request.getRemoteAddr();
  
  
   //if(clientIP==null||clientIP.equals(""))
 // throw new FusionException("Client IP is Null or empty");
       logDebug(this,"fusionPerform","Client IP from WL-Proxy-Client-IP : " + wlproxyclientIPheader);
   logDebug(this,"fusionPerform","Client IP from Proxy-Client-IP : " + proxyclientIPheader);
   logDebug(this,"fusionPerform","Client IP from getRemoteAddr():" + clientIPrequest);
       String clientIP ="";
       //if(!(wlproxyclientIPheader==null||wlproxyclientIPheader.equals(""))){
//logDebug(this,"fusionPerform","Client IP is from WL-Proxy-Client-IP : " + wlproxyclientIPheader);
       //clientIP=wlproxyclientIPheader;

       //}
       clientIP= clientIP.substring(0,clientIP.lastIndexOf("."));
   logDebug(this,"fusionPerform","First 3 parts of Client IP: " + clientIP);
   ResourceBundle rb =ResourceBundle.getBundle("DNS_"+domain);
           
           String dnsKey=curHost+"."+clientIP;
           logDebug(this,"fusionPerform","dnsKey: " + dnsKey);
           String http ="http://";
           boolean flag=false;
   Enumeration e=rb.getKeys();

have you tried opening the URL without the www in a browser? If the redirection is happening on the server (eg being sent a 301 or 302 response code) you will need to take that into account in your code.
