> Now server call method as a goroutine to check cancel flag.
> When the Cancel() method is called the cancel flag is set to the cache as a 
> true.
> Need:
>  * Set false flag as a default value before calling the Process method.
>  * Change the logic of the cancelCheck() method. Now it checks that the flag 
> cancel exists and after that returns from the method and stops goroutine. 
> Need to change this logic and return from the method in case the cancel flag 
> is true.
