f68f1ed56d2772022b2211de5c8094d0f6f63bd1 Compression dictionaries ignore stale-while-revalidate
not a security fix
confidence 0.15
signal score 6.3
Source/WebKit/NetworkProcess
Classified as not security-relevant.
Triage note: processUseAsDictionaryHeader now returns early on Cache-Control:no-cache and adds stale-while-revalidate to the dictionary lifetime (RFC 9842). HTTP cache freshness correctness for compression dictionaries; no clear security bug.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
