We observed that huge % of Atmosphere REST method invocation time is taken for contacting MI every time user is invoking Atmosphere REST method (more/less 68% percentage of invocation time). To improve this situation we created 5 minutes cache for the ticket. It works fine, but we want more :) We want to extend cache entry every time user is using the same ticket. To do so we need to have ticket expiration date. Can you add it into returned json?
