@Iprogrammerr Hi Igor! Thanks for your comment. Actually I'm working in big change API and implementing the simple caching API. After that, I'll develop this feature.

@fabriciofx I understand. When you finish you could describe its requirements here/in other ticket and I will be happy to contribute.
