Catalyst::Plugin::XSendFile - Catalyst plugin for lighttpd's X-Sendfile.

use Catalyst qw/XSendFile/;
# manual send file
sub show : Path('/files') {
my ( $self, $c, $filename ) = @_;
# unless login, it shows 403 forbidden screen
$c->res->status(403);
$c->stash->{template} = 'error-403.tt';
# serving a static file only when user logged in.
if ($c->user) {
$c->res->sendfile( "/path/to/$filename" );
}
}
# auto using x-send-tempfile on large content serving
MyApp->config->{sendfile}{tempdir} = '/dev/shm';

This developer version of module requires lighttpd 1.5.0 (r1477) or above.

lighty's X-Sendfile feature is great.
If you use lighttpd + fastcgi, you can show files only set X-Sendfile header like below:
$c->res->header( 'X-LIGHTTPD-send-file' => $filename );
This feature is especially great for serving static file on authentication area.
And with this plugin, you can use:
$c->res->sendfile( $filename );
instead of above.
But off-course you know, this feature doesn't work on Catalyst Test Server (myapp_server.pl). So this module also provide its emulation when your app on test server.

Latest version of lighttpd (1.5.0) also support X-LIGHTTPD-send-tempfile, that is almost same to X-LIGHTTPD-send-file except deleting sending file when server sent file.
This module automatically use this feature when content length is above 16kbytes.
And for more performance, you need to set tempdir ($c->config->{sendfile}{tempdir}) on tmpfs (/dev/shm).
See below urls for detail.

Faster - FastCGI http://blog.lighttpd.net/articles/2006/11/29/faster-fastcgi

To use it you have to set "allow-x-sendfile" option enabled in your fastcgi configuration.
"allow-x-send-file" => "enable",
or on 1.5.0:
proxy-core.allow-x-sendfile = "enable"

Setup tempdir for x-send-tempfile
Serving large (16kbytes) content via X-LIGHTTPD-send-tempfile.

Set X-LIGHTTPD-send-file header easily.
