Is there a gateway setting to redirect to subdomain before fetching? If not this should be a config option

I noticed that 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.

iirc redirecting to subdomain before resolving things was proposed in IPIP-386, which got accepted and is now the default behavior since Kubo >=0.22

So you may want to update to the lastest one and see if that helps:
