I am using apache2.4.6 and tomcat8 to implement a load balance solution.
I'd like to know whether apache balancer will redirect requests to another balancer member if it gets timeout error from one server.
For example, apache sends one request to tomcat1 but tomcat1 cannot respond within 10 seconds, will apache resend this request to tomcat2?
Below is my configuration for apache proxy balancer.
<Proxy balancer://myCluster timeout=10 failontimeout=on>
BalancerMember http://server1:8080 route=tomcat1 loadfactor=1 timeout=10 retry=30
BalancerMember http://server2:8080 route=tomcat2 loadfactor=1 timeout=10 retry=30
ProxySet lbmethod=byrequests
# ProxySet stickysession=JSESSIONID
Order Deny,Allow
Deny from none
Allow from all
</Proxy>

I belive you can achieve this feature by using second tomcat server as a hot standby. This is supported with mod_proxy in apache
You can try following configuration & test it.
