X-Accel-Buffering, proxy_buffering and proxy_store

[Michał Jaszczyk]

Hi,

Guys, any help about this? I still haven't figured anything... I
couldn't find it in the documentation and nothing came out of trying
to read Nginx source code...

Moreover, there's another question to it: Can I use FLV module in my
configuration?

Cheers,

Mike
