Apache Reverse Proxy configuration - Subdomains - apache

Question

I am trying to configure an Apache server to have 2 subdomains making use of a reverse proxy. I am able to redirect traffic to the first subdomain (first.example.com) and retrieve content from the https site successfully. However, whenever I try to access the second subdomain I end up getting content from the first, and since routes don't match my local website, I get a not found page.
I would like to know what can I adjust from my current configuration so I can get content from my localhost site to.
Here is my current configuration:
<Proxy *>
Require all granted
</Proxy>
SSLProxyEngine On
ProxyRequests Off
SSLProxyCheckPeerCN off
SSLProxyCheckPeerExpire off
SSLInsecureRenegotiation on
SSLProxyVerify none
SSLVerifyClient none
SSLProxyCheckPeerName off
<VirtualHost first.example.com:80>
ServerName first.example.com
ProxyPass /first https://stackoverflow.com
ProxyPassReverse /first https://stackoverflow.com
ProxyPassMatch ^/(.*)$ https://stackoverflow.com/$1
</VirtualHost>
<VirtualHost second.example.com:80>
ServerName second.example.com
ProxyPass /site http://localhost/site
ProxyPassReverse /site http://localhost/site
ProxyPassMatch ^/(.*)$ http://localhost/site/$1
</VirtualHost>
Thank you very much in advance!
Best Regards!

Your current configuration is conflicting with itself. ProxyPass and ProxyPassMatch does the same thing (in regex) but you declared it both with different rules.
ProxyPass /site http://localhost/site
Rule says: anyone that visits http://second.example.com/site will be fed content from http://localhost/site. If you visit http://second.example.com/foo, you get nothing.
The match line
ProxyPassMatch ^/(.*)$ http://localhost/site/$1
Rule says: Anyone that visits http://second.example.com/site will be fed content from http://localhost/site/site. If you visit http://second.example.com/foo, you get http://localhost/site/foo.
If you use the Match version (regex), you're also out of luck for the reverse rule which doesn't have a regex version. Though, I'm not certain you actually need the reverse rule.
As to why your second request got result from the first... I have no idea.
