Context path on Apache reverse proxy for multiple backend services - apache

Question

I have a setup for an apache reverse proxy for multiple applications as below:
https://serverxx:8000 -> http://localhost:9000
https://serverxx:8001 -> http://localhost:9001
https://serverxx:8002 -> http://localhost:9002
There are 3 virtual hosts files under /etc/httpd/conf.d/ which accomplishes this setup, and they look like the following:
Listen 8000 https
<VirtualHost *:8000>
ProxyPreserveHost On
SSLProxyEngine on
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/server.crt
SSLCertificateKeyFile /etc/pki/tls/private/server.key
Header always set Strict-Transport-Security "max-age=63072000; includeSubdomains;"
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
ProxyPass / http://localhost:9000/
ProxyPassReverse / http://localhost:9000/
</VirtualHost>
Due to new requirements, there needs to be some overhaul. The 3 applications which are accessible via https://serverxx:800[0,1,2] should now look like this:
https://serverxx/app1 -> http://localhost:9000
https://serverxx/app2 -> http://localhost:9001
https://serverxx/app3 -> http://localhost:9002
In other words, serverxx will only be listening on 1 port (443) and have 3 different context paths for 3 different proxied services.
Is this possible at all? I have been reading on https://httpd.apache.org/docs/2.4/vhosts/examples.html but couldn't get a definite answer.
Thanks in advance.

Answer 1

I have finally figured this out.
For those who are interested with an answer, the key is to add multiple ProxyPass and ProxyPassReverse values for each context path pointing to multiple backend servers.
Listen 8000 https
<VirtualHost *:8000>
ProxyPreserveHost On
SSLProxyEngine on
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/server.crt
SSLCertificateKeyFile /etc/pki/tls/private/server.key
Header always set Strict-Transport-Security "max-age=63072000; includeSubdomains;"
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
ProxyPass /app1 -> http://localhost:9000
ProxyPassReverse /app1 -> http://localhost:9000
ProxyPass /app2 -> http://localhost:9001
ProxyPassReverse /app2 -> http://localhost:9001
ProxyPass /app3 -> http://localhost:9002
ProxyPassReverse /app3 -> http://localhost:9002
</VirtualHost>
