problems with posting to this group). Hope it's OK for you.

Cheers,

Subject: Backend handling of Expect: 100-Continue header
To: nginx@nginx.org


Hi!

I searched through archives and I see that topic appeared on the list
in the past but I did not find
any concrete answers.

We use nginx to proxy large PUT (100M+) requests to backend servers.
When issuing an request clients sets "Expect: 100-Continue" header.

We noticed that nginx does not forward request to backend server until
it consumes it completely.
That is not what we want.

1. We need to disable automatic 100-Continue handling in nginx.
Instead we need nginx to forward headers to backend server and let it
determine if 100 Continue or final error code should be returned to
client.
2. We need to disable request body buffering as we have upload request
resuming implemented on the backend tier.

Are above achievable in current nginx version (maybe with some 3rd
party modules)? AFAIK mogilefs module proxies uploaded file directly
to backend servers withouth buffering.

Regards, Łukasz Osipiuk
