DNS Cache question

[metablaster]

Under "Advanced settings" there is "DNS Cache" option.

Can you please explain, is this cache a separate DNS cache that is maintained by dnscrypt-proxy, or is this DNS cache belonging to Windows OS?

I ask this because I want to clear the cache, if it's cache by OS, then simply Clear-DNSClientCache in PowerShell will do, however if it's cache maintained by dnscrypt-proxy, then how do you clear it?

This is an abandoned issue list.
There is anybody other than 'you' the author who can answer your question.
Let me ask you what the relationship between SimpleDnsCrypt and dnscrypt-proxy because I don’t think you know exactly the behavior to clear cache using ordinary DNS software.
Most DNS software will restart itself when a user want to clear its only states set: the cache.
Unfortunately dnscrypt-proxy belongs to ordinary DNS software and SimpleDnsCrypt is just another modern UI for it which spends/maintains more LOCs (source lines of code) than its couple.
