sudo vi /etc/apache2/sites-available/000-default.conf

<VirtualHost *:80>
  ServerName test_server1
  ProxyRequests Off
  ProxyPreserveHost On
  ProxyPass /deeplink http://localhost:8080 // 방법1
  ProxyPassReverse /deeplink http://localhost:8080
  
  <Location /user> //방법2
    ProxyPass http://localhost:8080
    ProxyPassReverse http://localhost:8080
  </Location>
</VirtualHost>

https

sudo vi /etc/apache2/sites-available/000-default-le-ssl.conf

<VirtualHost *:443>
  SSLProxyEngine On
  SSLProxyVerify none
