Apache

Apache configuration for a Plone backend deployed under /api and a Volto frontend deployed under the root /. This configuration also redirects http -> https.

<Proxy balancer://plonebackend>

  ProxySet lbmethod=bybusyness
  BalancerMember http://127.0.0.1:8001

</Proxy>

<Proxy balancer://voltofrontend>
  # Use Pending Request Counting Algorithm (s. http://httpd.apache.org/docs/current/mod/mod_lbmethod_bybusyness.html).
  # This will reduce latencies that occur as a result of long running requests temporarily blocking a ZEO client.
  # You will need to install the separate mod_lbmethod_bybusyness module in Apache 2.4.
