NAME

Plack::Middleware::XSendfile - Sets X-Sendfile (or a like) header for frontends

SYNOPSIS

  enable "Plack::Middleware::XSendfile";

DESCRIPTION

When the body is a blessed reference with a "path" method, then the return value of that method is used to set the X-Sendfile header.

The body is set to an empty list, and the Content-Length header is set to 0.

If the X-Sendfile header is already set, then the body and Content-Length will be untouched.

You should use IO::File::WithPath or Plack::Util's "set_io_path" to add "path" method to an IO object in the body.

See <http://github.com/rack/rack-contrib/blob/master/lib/rack/contrib/sendfile.rb> for the frontend configuration.

Plack::Middleware::XSendfile does not set the Content-Type header.

CONFIGURATION
