Plack::Middleware::CustomErrorDocument - dynamically select error documents based on HTTP status code
version 0.002
# 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; };
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.
$env
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).
