Description

Domino keeps HTTP connections open with Keep-Alive so that subsequent requests can be served without a new TCP/TLS handshake. HTTPMaxRequestsPerPersistentConnection defines the upper bound per connection – after that, the socket is closed, which frees memory and relieves load balancers from long-lived connections.

Example configuration

HTTPMaxRequestsPerPersistentConnection=200

Notes & pitfalls

  • Value 0 = unlimited – not recommended.
  • The default of 100 is enough in most cases; for API / REST loads, 200–500 can make sense.
  • Pairs with HTTPKeepAliveTimeout and HTTPMaxConnections.
  • With an upstream reverse proxy, this is usually limited on the proxy side as well.
  • The change takes effect after a restart of the HTTP task.
