The PR title contains a typo: 'bandwidht limit' should be 'bandwidth limit'.

Extra blank line at line 133 should be removed to maintain consistent spacing in the configuration file.

The HAProxy configuration example in the documentation uses a different syntax than what's implemented in the actual haproxy.cfg file. The documentation shows key and table parameters that aren't used in the actual implementation.
