Disclaimer: These are just my thoughts. I don't work for Protocol Labs (company behind IPFS) anymore and am in that sense just an IPFS enthusiastic dev that tries to make it more usable.
Hi, An IPFS URL passed to a gateway, like this (safe to try, it's big buck bunny): ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi Can be translated by the gateway in two ways (path [1] and subdomain [2]). The path version looks like: - http://localhost:8080/ipfs/bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi The subdomain variant looks like: - http://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi.ipfs.localhost:8080 The way IPFS gateways currently work by default (configurable in its settings) is to redirect the path based version to the subdomain based one. In a web browser context, where IPFS is used most, this all makes perfect sense! A consequence of this default is that a curl command like can work and fail: curl ipfs://bafybeigagd5nmnn2iys2f3doro7ydrevyr2mzarwidgadawmamiteydbzi If the gateway curl found is going to redirect then the above will fail and "-L" (follow redirect) needs to be added to the command. On the IPFS gateway side of things we're now playing with the thought to add the ability to make the gateway behavior explicit. For example, we're thinking of adding a header like: Ipfs-Gateway-Mode: path | subdomain If you'd pass the header: Ipfs-Gateway-Mode: path Then the gateway would honor this request (no redirect to subdomain) and give you the data you've requested. Thus far none of this would require any change in curl. However, we're wondering if it would be acceptable for curl to set this header by default for the ipfs/ipns schemes? It changes nothing with regard to follow redirects. Instead it's a hint to the gateway to not redirect at all and just give the data back as-requested. Not having to pass this header in curl is a big win in terms of user friendliness, but it comes at the cost of implicitly adding a header. I'm curious how the devs here think about this and if it would be acceptable?
