1671182 - Remove "cache" feature from Clear-Site-Data

Status: RESOLVED FIXED

(Toolkit :: Data Sanitization, defect, P3)

Description

[Anne (:annevk)]

As discussed at https://github.com/privacycg/storage-partitioning/issues/11#issuecomment-662932069 the "cache" feature has numerous problems and we likely shipped it too soon. Fortunately removing it is extremely unlikely to break anything.

(The main task here is probably updating test expectations.)

Reflecting our discussion, the cache clearing is now gated behind a flag, privacy.clearsitedata.cache.enabled.

Depends on D126006

FYI Docs work for this done in https://github.com/mdn/browser-compat-data/pull/13974 and https://github.com/mdn/content/pull/11505

The important bit is the compatibility data. That isn't "live" yet, but will indicate the existence of the preference / spec incompatibility at the bottom of https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Clear-Site-Data#browser_compatibility

(This bug seems to have been mis-filed; ClearSiteData.cpp lives in Toolkit :: Data Sanitization.)
