I am responding with a large (10 MB) payload from node.js to an Akka spray.io based actor, and getting a chunk size error from spray/akka [akka://spray-actor-system/user/IO-HTTP/group-0/3] Received illegal response: HTTP chunk size exceeds the configured limit of 1048576 bytes.
My node.js code just plainly sends off the response in one res.end command. (It does so because the response is generated in a non-streamed way and therefore there has been no "inherent" gain in streaming it further along, at least up until a spray.io client-side was added).
I am wondering what's the simplest way to chunk the response using node.js api, in case I prefer not handling very large http responses by increasing the spray.io size limit. Also whether there's any performance downside in sending responses this size from node.js - i.e. does node.js block on the res.end operation?
