Try this:when HTTP_REQUEST {
&nbsp;
   set NEW_URI "/resource2"
&nbsp;
   switch -glob [string tolower [HTTP::uri]]
&nbsp;
   "/resource1"
&nbsp;
    {
&nbsp;
     HTTP::respond 301 Location "https://[HTTP::host]$NEW_URI"
&nbsp;
    }
&nbsp;
   }

Can you define what is not working. Hows the flow going to and fro and what is being seen and what are you expecting. The above shared should do the trick unless something is rewriting it and goes unexpected.

Hi Jaikumar,The expected goal is as below:Option 1:From client to LB:https://www.domain1.com/resource1&nbsp;From LB to the server:https://www.domain1.com/resource2&nbsp;If the above option is difficult to achieve it then we can try for the below option:Option2:From client to LB:https://www.domain1.com/resource1&nbsp;From LB to the client with redirection 301:https://www.domain1.com/resource2&nbsp;I have tried irule for both the option and the results are as below:Option 1: all the URI values are replaced with the value of /resource2&nbsp;Option2: I'm getting blank page&nbsp;Could you please help me to identify if i'm missing something to meet my objective?&nbsp;Regards,Thiyagu&nbsp;&nbsp;

"Option 1: all the URI values are replaced with the value of /resource2"

You mean the query string? or there are also more folders?

Do you the client to be redirect, or juts change the URL on the way to the server?
