What are sticky sessions and how to configure them with Istio?

The idea behind sticky sessions is to route the requests for a particular session to the same endpoint that served the first request. That way to can associate a service instance with the caller, based on HTTP headers or cookies. You might want to use sticky sessions if your service is doing an expensive operation on first request, but later caching the value. That way, if the same user makes the request, the expensive operation will not be performed and value from the cache will be used.
