I’ve been using blanket rule of no-www this past years and that is coming to an end.
Leaking WordPress cookies to every single sites hosted on this domain is probably not the best idea. Not that there’s any problem but just in case. Also no cookie to worry about for uploads and other static sites. Or maybe not if WordPress sets the cookie properly (it seems to be mostly does).
I was thinking of moving everything but for some single-use domains like
0paste.com it’s probably fine with no-www.
The other benefit is I can point the bare domain to a cheap server just for redirection and properly set CNAME for
www subdomain instead of relying Cloudflare’s top-level CNAME function (which apparently also called “ANAME”?).
I’ve switched the redirection for www to 302 (temporary redirect) from 301 (permanent redirect) a while ago so hopefully no browser still cache the 301.
