Description
This PR adds
Cache-Control
headers to JWKS endpoint requests to ensure fresh keys are always fetched from the authorization server instead of potentially stale cached versions from HTTP-level caches (e.g., browser cache, proxies, CDNs), while preserving application-level caching inlocalStorage
.What Problem Does This Solve?
When keys are rotated at the authorization server, HTTP-level caching can cause the SDK to continue using stale keys, which may lead to token validation failures.
Changes Made
Cache-Control: no-cache, no-store, max-age=0

Security Impact
Positive: Reduces the window of vulnerability when keys are rotated by ensuring fresh keys are always used for token validation.
