NAME

Plack::Middleware::CustomErrorDocument - dynamically select error documents based on HTTP status code

VERSION

version 0.002

SYNOPSIS

# in app.psgi

$app = Plack::Middleware::CustomErrorDocument->wrap(
    $app,
    # dynamic $path (set according to $env):
    404 => sub {
        my $env = shift;
        ...
        return $path;
    },
    # use static path
    500 => sub { 'path/to/error/doc' },
);

# or with Plack::Builder:
builder {
    enable "Plack::Middleware::CustomErrorDocument",
        404 => sub {
        ...;
    };
    $app;
};

DESCRIPTION

Dynamically select an appropriate error document for an HTTP status error code. Pass in a subroutine coderef, which should take $env as the sole argument, and return the destination file path as a string.

An example use would be to return a 'missing' image file for image requests that result in a 404 status (and a standard 404 HTML page for all others).
