I hope the following is enough information. I have posted previously but I still haven't managed to resolve the problem.

Problem
I have 2 servers running Win 10 Pro & WAMP

I want to use Server1 as a proxy server & serve a website from Server2 via port 80 on Server1.

In summary, I want the following:-

www.myexample.com from Server 1 (working)
Demo.myexample.com from Server 1 (working)

newapp.myexample.com (problem) via Server 2
www.anotherexample.com (next problem) via Server 2


Current Setup
Server1: Windows 10 Pro (internal IP 192.168.0.31)
WAMP Apache V2.4.46
Connected to internet via modem and listening on port 80 & 443
‘Hello world’ test page working correctly via www.myexample.com
‘Hello Demo’ test page working via demo.myexample.com

This is the httpd.vhosts.conf for these 2 working
__________________________________________________
#Virtual Hosts on HTTPD-vhosts.conf - working fine

<VirtualHost *:80>
ServerName localhost
ServerAlias localhost
DocumentRoot "${INSTALL_DIR}/www/"
<Directory "${INSTALL_DIR}/www/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require all granted
</Directory>
</VirtualHost>


#localhost for demo working fine
<VirtualHost *:80>
ServerName local.demo
DocumentRoot "c:/wamp64/www/demo"
<Directory "c:/wamp64/www/demo/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>

#demo.myexample.com working fine
<VirtualHost *:80>
ServerName demo.myexample.com
DocumentRoot "c:/wamp64/www/demo"
<Directory "c:/wamp64/www/demo/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
_______________________________

This all works correctly therefore DNS a records, external IP address, firewalls are correctly configured.

Server2: Windows 10 Pro (internal IP address 192.168.0.7)
WAMP Apache V2.4.46
Reverse Proxy installed correctly same as Server 1

Website is served correctly via 192.168.0.7/newapp from localhost and server can be pinged from Server 1

newapp site also successful via http://192.168.0.7/newapp from Server2 on the internal network

Document folder is C:\wamp64\www\newapp\

Help Required
I have tried many different entries in httpd.vhosts.conf on Server1 to direct newapp.myexample.com to Server 2 then return to publish the page via Server1. I understand it needs to be a named or IP based reverse proxy but no luck.

Any help much appreciated as I am new to this area

Below is one example I tried but with no luck.

#newapp.myexample.com - not working
<VirtualHost *:*>
ProxyPreserveHost On
#
# # Servers to proxy the connection, or;
# # List of application servers:
# # Usage:
# # ProxyPass / http://[IP Addr.]:[port]/
# # ProxyPassReverse / http://[IP Addr.]:[port]/
#
# # Example:
ProxyPass / http://192.168.0.7/
ProxyPassReverse / http://192.168.0.7/
# <Directory "c:/wamp64/www/newapp/">
# Options +Indexes +Includes +FollowSymLinks +MultiViews
# AllowOverride All
# Require all granted
# </Directory>
# ServerName newapp.myexample.com
#</VirtualHost>


Thanks

You say your Server 2 content is from http://192.168.0.7/newapp so have you tried using a <Location> section to contain your proxy pass directives (including a /newapp suffix), e.g.

Code:
    <Location /newapp>
        ProxyPass http://192.168.0.7:80/newapp
        ProxyPassReverse http://192.168.0.7:80/newapp
    </Location>

See https://httpd.apache.org/docs/current/mod/mod_proxy.html#proxypass for details, taking note of the comments over trailing slashes.
