Acrylic DNS Hosts not refresh
Solution 1:
The AcrylicHosts.txt file is reloaded each time the Acrylic service starts.
AFAIK the only other caches involved are the DNS client cache, which can be invalidated by the 1ipconfig /flushdns1 command, and, eventually, your browser's own DNS cache.
For example in Chrome you can access its contents by navigating to:
chrome://net-internals/#dns
