7       status code
8

SYNOPSIS

10         # in app.psgi
11         use Plack::Builder;
12
13         builder {
14             enable "Plack::Middleware::ErrorDocument",
15                 500 => '/uri/errors/500.html', 404 => '/uri/errors/404.html',
16                 subrequest => 1;
17             $app;
18         };
19

DESCRIPTION

21       Plack::Middleware::ErrorDocument allows you to customize error screen
22       by setting paths (file system path or URI path) of error pages per
23       status code.
24

CONFIGURATIONS

26       subrequest
27           A boolean flag to serve error pages using a new GET sub request.
28           Defaults to false, which means it serves error pages using file
29           system path.
30
31             builder {
32                 enable "Plack::Middleware::ErrorDocument",
33                     502 => '/home/www/htdocs/errors/maint.html';
34                 enable "Plack::Middleware::ErrorDocument",
35                     404 => '/static/404.html', 403 => '/static/403.html', subrequest => 1;
36                 $app;
37             };
38
39           This configuration serves 502 error pages from file system directly
40           assuming that's when you probably maintain database etc. but serves
41           404 and 403 pages using a sub request so your application can do
42           some logic there like logging or doing suggestions.
43
44           When using a subrequest, the subrequest should return a regular
45           '200' response.
