Access log certainly can be configured to provide enough
enformation to match any given error log message to a port if
needed. There is no need to implement anything, solution is
And, by asking about "why implement a partical solution" you are
overlooking the fact that proposed solution is partial as well -
it doesn't change c->addr_text to ensure proper logging in all
places (this would be a bad idea for other reasons, but it's
another question), but rather tries to hack on the http error
logging code to introduce remote port logging. This is far from
being a complete solution.
