Not sure which OS you are using but it is customary to do the following:
- Enable the modules:
a2enmod proxya2enmod proxy_http. - In your case, you want to use AJP so you probably have to install a thing or two (e.g.
a2enmod proxy_ajp). - In your Virtual Host (you can do
http.confbut it's not the most flexible way).
This is what you have copied from your question:
<Proxy balancer://testcluster stickysession=JSESSIONID>
BalancerMember ajp://localhost:8109 min=10 max=100 route=server1 loadfactor=1
BalancerMember ajp://localhost:8209 min=20 max=200 route=server2 loadfactor=1

ProxyPass / balancer://testcluster/
This is how I do it (not much different):

I know this is an old question, but maybe the answer is helpful to others.
The module names of the last two loaded modules are wrong. mod_proxy_ajp.so is loaded as proxy_module and mod_proxy_balancer.so as proxy_http_module.
wrong:
LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy_ajp.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_balancer.so
right:
LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so
