Your application is supposed to work with any PSGI servers without any
code modifications, but if your application uses $c->res->write
to do streaming write, this engine will buffer the ouput until your
To do real streaming with this engine, you should implement an
IO::Handle-like object that responds to getline method that returns
chunk or undef when done, and set that object to $c->res->body.
Alternatively, it is possible to set the body to a code reference,
which will be used to stream content as documented in the
When your application runs behind the frontend proxy like nginx or
lighttpd, this Catalyst engine doesnt automatically recognize the
incoming headers like X-Forwarded-For, because respecting these
headers by default causes a potential security issue.
You have to enable Plack::Middleware::ReverseProxy or
Plack::Middleware::ForwardedHeaders to automatically promote those
forwarded headers into REMOTE_ADDR hence IP address of the request.
ReverseProxy middleware is pretty simple and has no configuration
while ForwardedHeaders allows you to configure which upstream host to
