The helper potocol is outlined at
<http://wiki.squid-cache.org/Features/AddonHelpers#URL_manipulation>.

Each 'key=' in the helper output gets appended to the HTTP transaction
as an annotation 'note'. The logging can display these via the
%note{key-name} format code.

For older helpers that use the pre-3.4 protocol without kv-pairs their
responses get mapped into the kv-pair format. So you should see the same
%note{url} or %note{rewrite-url} annotations at logging time even with
older helpers.
