How to keep the internal URL in browser address bar and point to external website

Is there a way to keep internal web address all the time and point it to public URL?   Let's say I have internal web address called honest2.company.com which has 10.10.2.35 and have public website...

That's a fairly basic problem and I recommend you look into LTM Local Traffic policy feature for the most performance-efficient solution. However, you can also use an iRule provided below. Of course, you will also need two DNS entries - one of which is used by the general public, the other for your private LAN users/employees.

when HTTP_REQUEST {
  if { ([HTTP::host] eq "abc123pqr456xyz789.azurewebsites.net") && (not ([class match [IP::client_addr] eq "private_net" ])) }{
    HTTP::header replace Host "honest2.company.com"
  }
}

This iRule is correct, all it does is it takes the original HTTP Host value and replaces it with your internal HTTP host. Probably an asymmetric routing issue as you try to hit the external DNS from your internal LAN. Responses might not return via the correct path. For testing purpose, temporarily enable SNAT Automap setting in Virtual Server settings and try again. You can revert it back afterwards.
