Dear Spyridon,
Thank you so much for your answer and help. It is a good trick to not reply
Interest with the cached data. However, as I understand data will not be
deleted from the cache so
in the case that I need to consider limited cache size, I may face a
problem in evaluating the method. I prefer this data will be deleted from
the cache so there will enough space for another data. If it does not mind,
may I know your another solution as well.
Thank you so much for time and help
Best regards
