Sorry, I missed a step in making the candidate resource list public. I
have moved it to my chromium account and made it public here

Not everything in that list meets all of the criteria - it's just the
first step in the manual curation (same URL served the same content
across > 20k sites in the HTTP Archive dataset).
The manual steps frome there for meeting the criteria are basically:
- Cull the list for scripts, stylesheets and compression dictionaries.
- Remove any URLs that use query parameters.
- Exclude any responses that set cookies.
- Identify URLs that are not manually versioned by site embedders
(i.e. the embedded resource can not get stale). This is either
in-place updating resources or automatically versioned resources.
- Only include URLs that can reliably target a single resource by
pattern (i.e. ..../<hash>-common.js but not ..../<hash>.js)
- Get confirmation from the resource owner that the given URL Pattern
is and will continue to be appropriate for the single-keyed cache
A few questions on list curation:
Can you clarify how big the list will be? The privacy review at
https://chromestatus.com/feature/5202380930678784?gate=5174931459145728 mentions
~500, while the design doc mentions 1000. I see the candidate resource
list starts at ~5000, then presumably manual curation begins to get to
one of those numbers.
What is the expected list curation/update cadence? Is it actually manual?
Is there any recourse process for owners of resources that don't want to
be included? Do we have documentation on what it mean to be appropriate
for the single-keyed cache?
thanks,
Mike
