Hey, i was given an http link for downloading a big file and was thinking if it is possible to find the file in IPFS, but for this i need to know the CID without downloading the full file. So i wonder if anyone thought about this already and maybe something was discussed and/or done in this direction.
The idea is to have a CID header in HTTP servers responses to HEAD requests. So any user can get the CID and check if the content is available via IPFS. The task seems quite simple to me: to implement CID calculation for served static files in major HTTP servers (apache, nginx, caddy, etc) and add the header for those responses. Of course, there is no need in this for dynamic data, so the servers just omit the calculation and the header.
