Users are not able to edit the web page on web server while traffic passes through the Load Balancer

Look very carefully at what the client is attempting to do. The working setup includes HTTP and HTTPS services, so it's assumed that some things are talking to the HTTP service and others the HTTPS service. Your client side capture should show the calls to both and you should see this in network captures (traffic going to port 80 and port 443). You may need to look inside the returned HTML and JavaScript payloads to find references to the HTTP service. If you can find where the HTTP service is being referenced, then you can work on fixing it. The above iRule should rewrite these references, but you won't know for sure until you find them.
