[undertow-dev] Proxy and chunking.

[Jocke Eriksson]

Thanks for all the input. Clearly we made a bad design decision a few years back. It is clear to me how to fix it and have a more compliant solution.

Regards

Hi devs and followers we have a problem and maybe someone on this list have some input.

We use undertow as an API gateway in front of JBoss application servers.
One API we have is responding with a chunked response, and the receiving side is expecting that each chunk is a valid JSon object.
When we analyze the TCP dumps it looks like some chunks are not the full JSon response we are expecting.

This is a terrible idea, chunking is an implementation detail of the HTTP transport layer. Proxies are allowed to change the chunk boundaries.


So the question is could this be a problem in the gateway?

I found a flag called PRE_CHUNKED_RESPONSE could this be the answer.
If so, how do we apply it in a proxy handler?

You can't really, the client the proxy uses will strip the chunk data, so the proxy will never see it, this would be a feature request.
