    Just a quick heads up for those of you with HTTPS sites wanting to use the DNS prefetch option of this plugin.

    Chrome browser by default does not do DNS prefetch on HTTPS sites, you need to add a header to turn it on if wanted.

    Chromium DNS prefetch

    Chromium watches for an HTTP header of the form “X-DNS-Prefetch-Control” (case insensitive) with a value of either “on” or “off.”

    As well as FireFox browser also by default does not do prefetch on HTTPS.
    Mozilla DNS prefetch

    Also, by default, prefetching of embedded link hostnames is not performed on documents loaded over HTTPS. On Firefox, this can be changed by setting the network.dns.disablePrefetchFromHTTPS preference to false.

    Etc etc…

    Cheers!
