Previous discussions here: Boundary node http response headers As far as I know, it is currently impossible to host podcasts with full functionality from a canister. I know because I’ve been hosting my podcast Demergence from a canister. Why doesn’t it work? Basically because boundary nodes have a…

Thanks for bring this up again. Let me get this some attention.

Hi @lastmjs , Sorry for the long delay in response. I am copying @raymondk Raymond (Sr. Eng Manager) who owns this part of the stack. We will modify BNs so they forward the range headers for the .raw endpoints, in order to unblock you and others like you. There are two things to note: It’s poss…

[image] diegop: In order to make this easier/faster for us to scope, can you share with us the canister + canister code from which you would stream your podcasts? We may also need your help testing. I have this fork of the assets canister from a while ago: cdk-rs/src/ic-certified-assets at ma…

Thanks for sharing the repo @lastmjs ! I think this is good for now. We should be able to use your code to verify that our changes are working properly.

[image] lastmjs: If the IC is going to be a general-purpose cloud, then I don’t think we should remove an entire valid class of http functionality. Some streaming may be more optimal in certain ways, but range requests are a valid way to perform various use cases. That pretty much was the dec…

No thank you, I appreciate all of this

It’s been a while, but now that Express is working in Azle I decided to deploy an example application to mainnet to test out audio and video streaming. It looks like the Range request header is being stripped out by the boundary nodes or somewhere along the chain, everything is working fine locally…
