kipedia.org/wiki/HTTP_persistent_connection">persistent HTTP connections when connecting (or reconnecting) to the SSE endpoint.

In case you are using Jersey event source with a Jersey client {@link org.glassfish.jersey.client.ClientConfig#connectorProvider(org.glassfish.jersey.client.spi.ConnectorProvider)}connector provider configured to use some other client {@code ConnectorProvider} implementation able to reliablymanage persistent HTTP connections (such as {@code org.glassfish.jersey.grizzly.connector.GrizzlyConnectorProvider} or{@code org.glassfish.jersey.apache.connector.ApacheConnectorProvider}), or in case you simply need to use persistent HTTP connections, you may do so by invoking the {@link Builder#usePersistentConnections() usePersistentConnections()} methodon an event source builder prior to creating a new event source instance.
