I'm while using following Apache config to forward demands to some Tomcat server:

ProxyPass /myapp ajp://localhost:8009/myapp max=2

This can be a simplified config, but is sufficient to reproduce the problem, which would be that the max parameter doesn't have effect. Basically through 10 concurrent demands to Apache, all 10 are submitted to Tomcat simultaneously, while I must ask them to submitted 2 by 2. Must I use something apart from the max parameter with this?

service apache2 restart
