HTTP 1.1 chunk-size computation algorithm

Question

This is rather a question to satisfy curiosity.

How does standard HTTP 1.1 stacks compute chunk-sizes on a HTTP response socket? Is it timeout based, max size based or depends on when the application does a flush on the socket, or an algorithm based on all of them? Is there any open HTTP 1.1 stack implementation guideline available on this?

Thanks in advance.

Answer 1

There is no "standard" HTTP/1.1 stack. Often you have to do it yourself, e.g. make sure a transfer-encoding: chunked header is send, then send all the chunks prefixed with length and then the last empty chunk.
