Can sniproxy receive proxy_protocol connections?

[dashohoxha]

Can sniproxy be behind another SNI proxy (maybe another sniproxy) which has enabled the proxy_protocol feature? Is sniproxy able to receive proxy_protocol connections?

I am testing with a sniproxy behind another sniproxy. It looks like this:

---> sniproxy1 ---> sniproxy2 ---> backend

I have enabled proxy_protocol on sniproxy2 and on backend and this works fine.
But when I try to enable proxy_protocol on sniproxy1, things break.
This seems reasonable to me because I expect that sniproxy2 needs to be configured so that it is able to receive proxy_protocol connections (instead of plain HTTPS). However I am not able to find any setting for this on the man page.

I guess that it should be a setting of listener, and it should look like this: protocol proxy_tls. However the only protocols supported (according to the man page) are protocol http and protocol tls.

Am I missing something?

No, there is not support for accepting connections with the proxy protocol header.

Maybe it is not too difficult to implement.
Anyway, sniproxy is a very nice tool, especially because its configuration is very simple.
