Hi everybody,

Nice work!

Here's my feedback (completely editorial):

>    An immutable response has the same semantic meaning when received by

>    Therefore proxies SHOULD skip conditionally revalidating fresh

Maybe point to Section 5.2.1.4 of RFC 7234 here...

>    A proxy that uses immutable to bypass a conditional revalidation may

s/may/MAY/ or s/may/can/

Maybe add a full example, including a request/response pair for the case 
when "immutable" is not present?
