with all log events arising from the request.
Rather than repeat the attribute with every log call, you can use [Logger.With]
to construct a new Logger containing the attributes:

	logger2 := logger.With("url", r.URL)

The arguments to With are the same key-value pairs used in [Logger.Info].
The result is a new Logger with the same handler as the original, but additional
attributes that will appear in the output of every call.
