size and memsize gives always 0 result

[Xgamefactory]

we have check cached data exists after put but keys returns empty result
also size and memsize is zero always

require("memory-cache").size() => 0
require("memory-cache").memsize() => 0

require("memory-cache").keys() empty array

[annibuliful]

require("memory-cache").size() always 0 because It's call module which is not stored into a variable

https://github.com/ptarjan/node-cache/blob/master/index.js#L102

You can see this function which returns the size of the cache

https://github.com/ptarjan/node-cache/blob/master/index.js#L25

Whenever you call put() to store your data into cache, the size is increased.
