Apache web server proxy pass and get original request server name in destination

Good day,

I have the flow as follow:

(public ip) 192.168.0.142 --> (192.168.111.66) web server --> (192.168.1.199) java web app server

In my 192.168.111.66 Apache web server, I have configure the following in my httpd.conf:

ProxyPass "/image.web" "https://192.168.1.199/image.web"
ProxyPassReverse "/image.web" "https://192.168.1.199/image.web"

The network successfully reach to my web app server (192.168.1.199), however, in my java web application, I saw the request is servername is 192.168.1.199, I believe this is because of my configuration in Apache Web Server, May I know how can I configure, so that in my java web application, I can detect the request servername is 192.168.0.142, which is the public ip.

Just found the answer:

ProxyPreserveHost On
