IPFS gateway redirect fails for HTTP redirects

[da2x]

DNS zone for example.com:
_dnslink TXT "dnslink=/ipfs/hash"

1. Enable DNSLink check before HTTP request
2. Visit a website that redirects from say example.com to www.example.com. The domain has DNSLink setup at the apex but not at the www subdomain.

Expected: Should redirect to local gateway.

Actual: Redirects to www.example.com and stays on the web.

Real-world example: https://nakhan.net/

Neither https://nakhan.net/ nor https://www.nakhan.net/ resolve valid DNSLink:

• https://ipfs.io/api/v0/dns/nakhan.net?r=true
• https://ipfs.io/api/v0/dns/www.nakhan.net?r=true

@da2x are you sure the website is set up correctly?
There are no TXT records defining DNSLink atm:

$ dig +noall +answer TXT _dnslink.nakan.net
$ dig +noall +answer TXT nakan.net
$ dig +noall +answer TXT www.nakan.net

If you want to see valid dnslink, check dig +noall +answer TXT _dnslink.docs.ipfs.io

ps. we are planning to stop redirecting DNSLink websites by default, see (B) of #667 – feedback/ideas will be appreciated.

He must have removed them. I contacted him about another issue with his DNSLink setup and it seems he just removed it instead of addressing it.

Fair enough.

I assume its misconfiguration or slow propagation similar to #659 so closing this, but free to reopen if it is possible to reproduce :)
