Plack::Middleware::XSendfile - Sets X-Sendfile (or a like) header for frontends
enable "Plack::Middleware::XSendfile";
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.
The header tag to use. If unset, the environment key plack.xsendfile.type
will be used, then the HTTP_X_SENDFILE_TYPE
header.
Supported values are:
X-Accel-Redirect
X-Lighttpd-Send-File
X-Sendfile
.
An unsupport value will log an error.
