- OS X: How to reset the DNS cache
- Windows (Vista): http://en.kioskea.net/faq/10548-vista-reset-the-dns-cache
- https://addons.mozilla.org/en-US/firefox/addon/dns-cache/ – has usability issues according to the reviews
- http://www.techiecorner.com/225/how-to-disable-firefox-dns-cache/ – go for the manual approach:
This is the manual approach for Firefox:
- Introduce 2 new variables within about:config:
- network.dnsCacheExpiration (integer / 0)
- and network.dnsCacheEntries (integer / 0);
- my problem with this: if you want to reset these switches, that’s fine with Firefox, just that they get their data types changed to “string“; and once, you want to set them again to “integer / 0“, you simply can’t; for the time being I just assume, Firefox doesn’t seriously consider the data type and accepts “string” for these 2 as well.
