How can we use ARRAffinity with AzFuncs?
Is PreferConnectionAffinity app setting still working? (as in https://meghnakharera.wordpress.com/2021/06/18/enable-disable-affinity-cookie-on-azure-function-app/)

Context: we need to invalidate a cache using an httphook/notification, and send the same trigger to each instance in the farm. Any other alternatives to this?
thank you

    Affinity works via a cookie. This means the call has to store the cookie and use it in subsequent calls. As the cookie will expire, the caller needs to renew.

    Not sure how this helps you. Your cache clear evoker would somehow have to be sure it’s connected once to all servers and track a cookie for each one. But it could also have multiple cookie to the same instance.
