This example connects http://pkg.example.com/myrepo to internal1.example.com:10000 and internal2.example.com:10000.
Configure the depot server with an appropriate proxy_base setting as shown in Configuring a Simple Prefixed Proxy.
Limit the number of back-end connections to the number of threads each depot is running divided by the number of depots in the load-balancer setup. Otherwise, Apache opens more connections to a depot than are available and they stall, which can decrease performance. Specify the maximum number of parallel connections to each depot with the max= parameter. The following example shows two depots, each running 200 threads. See Configuring a Simple Prefixed Proxy for an example of how to set the number of depot threads.
<Proxy balancer://pkg-example-com-myrepo>
# depot on internal1
BalancerMember http://internal1.example.com:10000 retry=5 max=100
# depot on internal2
BalancerMember http://internal2.example.com:10000 retry=5 max=100
</Proxy>
