        // True-Client-IP has the value when the request is coming via the caching integration.
        ipAddress = ApexPages.currentPage().getHeaders().get('True-Client-IP');
        
        // X-Salesforce-SIP has the value when no caching integration or via secure URL.
        if (ipAddress == '' || ipAddress == null) {
            ipAddress = ApexPages.currentPage().getHeaders().get('X-Salesforce-SIP');
        } 
        
        // get IP address when no caching (sandbox, dev, secure urls)        
        if (ipAddress == '' || ipAddress == null) {
            ipAddress = ApexPages.currentPage().getHeaders().get('X-Forwarded-For');
