----------------------------------------
Successfully applied the patch and built, but the results are just the same. On my current
testbed I can generate 404's by simply clicking refresh in the browser at a rate of
4/second... During this one-thread testing this seems to be the relevant part of
error.log:

Please note, that the url I'm using here is not the load-balancer demo application,
but another webapp hosted on the worker nodes. The behavior is the same as of the demo
app.
