Stop Meteor Call when leaving the calling template


#1

I have got the following problem. I am using Meteor.call to make HTTP calls from the backend to some third party APIs. Apparently they take pretty long responding which is not actually the problem.
The problem is that when a user leaves a template and the Meteor call which was made becomes unnecessary is not stopped and takes computing and waiting time on the backend allthough the nothing is done with the data coming back.
Is there a way to cancel Meteor calls when a user leaves the template making the call?
