Steps to Reproduce:
Hide

1. Set up access logging to include an incoming header:

<access-log prefix="access." pattern="%h %l %u %t %r %s %b %{i,X-Forwarded-For}"/>

2. Attempt a request with multiple header occurrences and note the logged results:

curl -H "X-Forwarded-For: 127.0.0.2" -H "X-Forwarded-For: 127.0.0.3" localhost:8080/app

The access log only logs the first occurrence of an incoming request header. This can hide desired or expected values from being logged.
