Web development often needs to switch between various host bindings. There is a DNS Flusher plug-in under firefox, but there is no chrome version. In fact, clearing the DNS cache under chrome is very simple:
1. Open with chrome: chrome://net-internals/ #dns
2. Click on "clean host cache" above,
for convenience, you can add a bookmark :)
