Hi @kbitra1998 ,

         You need to add something in configuration like below.

APACHE CONFIGURATION FILE: /etc/httpd/conf.d/httpd.conf

<IfModule remoteip_module> RequestHeader edit X-Forwarded-For ([0-9]+(?:\.[0-9]+){3})(:[0-9]+)? $1 early # valid for ALB, ELB, AppGateway or Load Balancer + CloudFront RemoteIPHeader X-Forwarded-For # valid for ALB, ELB, AppGateway or Load Balancer + Akamai RemoteIPHeader True-Client-IP </IfModule>

The above change will make sure the user’s IP address is added to the request header. The name of the header is X-Forwarded-For. 

 

Also, the header will have 2 IP addresses ( comma separated ). We have to make sure we read the first IP address from the CSV string.

    Hi @sanjay_bangar ,

     

    I have added the code snippet in https.conf, but still I'm not seeing the x-forwarded-for in developer tools. will it be visible in developer tools - request headers?

      Hi @kbitra1998 

       

      You can write one Util class in JAVA and add the following code into it.

       

      public static String getClientIPAddress(HttpServletRequest request) {
          String xForwardedForHeader = request.getHeader(HttpHeaders.X_FORWARDED_FOR);
          if (xForwardedForHeader == null) {
              return request.getRemoteAddr();
          } else {
              return new StringTokenizer(xForwardedForHeader, ",").nextToken().trim();
          }
      }

       

       This will always return the client IP address irrespective of ALB, ELB, CDN whatever.

       

      Thanks!

        Hi Asutosh,

         

        I have added the below snippet in conf file. but still, I'm not seeing the X-Forwarded-For in the browser developer console. is it something x-Forwarded-For will not visible in the browser?

         

        <IfModule remoteip_module> RequestHeader edit X-Forwarded-For ([0-9]+(?:\.[0-9]+){3})(:[0-9]+)? $1 early # valid for ALB, ELB, AppGateway or Load Balancer + CloudFront RemoteIPHeader X-Forwarded-For # valid for ALB, ELB, AppGateway or Load Balancer + Akamai RemoteIPHeader True-Client-IP </IfModule>

        Vijay

          Hi @vijayselvas1 

           

          This code will be executed at server side and you will never be able to read the IP address on browser console. If you want to read the IP address on clientside, you will need to make an AJAX call and get the IP address and populate it on the frontend.

           

          But why you want to read the IP address at clientside? What exact functionality you are expecting here?

           

          Thanks!


          Hi @asutosh_jena_ ,

           

          I wanted to read the user IP address in server side and for specific IP I just wanted to have some logic. Since I have added the x-forwarded-for in dispatcher, I thought it will be visible in request-header section in developer tools. Let me try to get the IP in server side.  Thanks
