Hi Undertow Developers
I am playing a little bit with the LoadBalancingProxyClient feature in
Undertow. I am looking for a solution that replaces my implementation of
a load balancer, which is based on Apache HttpClient.
The LoadBalancingProxyClient fulfills almost the functionality I need.
Do you have a plan for these two features?
1. To make tho host selection configurable. Currently, it is a static
round robin strategy. I think this is a simple task and I was able
to change the code so that this host selection is configurable.
For now you can override the selectHost() method. Its not a great
solution though. Can you file a JIRA to make this pluggable?
2. The second feature is much more difficult for me to solve. I need a
failover to the next host also in case the backend server responds
with say a status code 503. The backend servers are based on the
clustered HA singleton pattern, meaning, there is one backend server
which is the master node. The other backend servers are up but
shouldn't get http request. If the inactive servers get a call, then
they will respond with 503.
Can you file a JIRA about this as well?
At the moment our focus with the proxy is getting mod_cluster support up
and working, however both these things should be relatively easy to
implement.

We use Wildfly for front and backend servers. It would really cool to
reuse all the undertow power:-)
Let me know what you think. I am certainly offer to help for whatever
you need. Testing for example.

Ralf
