Description Domenico Briganti 2019-11-25 09:01:53 UTC

I've configured an Apache HTTPd as a load balancer to forward request towards two instances of ApplicationServer, using mod_proxy, mod_proxy_balancer and mod_lbmethod_byrequests. 
I started only one ApplicationServer.
When the mod_proxy sends a request to power off node understand that this is not alive and send the same request to other (live) node, but with an empty body.

I've prepared a test case on github to verify the bug: 

https://github.com/dometec/apache_modproxy_bug

The body of the POST Request is less 2KB (30 byte in the test case on github).

This should be already fixed in trunk by r1869216 and r1869224. Can you please verify?

2.4.x backport proposed in bug 63891, switching there.
