I noticed that dweb.link redirects to subdomain without fetching, this is very desirable because for example if you fetch 7 slow IPNS records in the browser from the same host, the 7th will be queued because of the max 6 connections per host.
Whereas if you redirect to subdomain before fetching, the redirect takes a few ms, then the long request uses its own subdomain so the max connection becomes 200.
