Control the Cache-Control header of the jwks_uri (https://{domain}.b2clogin.com/{tenant}/{policy}/discovery/v2.0/keys)

Hi,

I'm using Azure AD B2C with custom policies.

when I'm using the keys endpoint (jwks_uri) it returns the keys response with the header: Cache-Control: private.
Is there a way to control it, maybe through the custom policies (I want to change it to public)?

I'm using an API gateway tool and I want to retrieve the keys once instead of fetching the keys for each call, and this header prevents me from doing so.

Thanks, Gil

    Currently cache-control is bye default private and it cannot be changed.
