So I have a simple Plack app that uses the ErrorDocument middleware to serve a custom error.

The app configures the middleware like this:

  enable 'ErrorDocument',
    403 => '/error/forbidden',
    404 => '/error/not_found',
    subrequest => 1,
  ;

This works great. However now I'd like to bypass this middleware in certain specific cases and serve an alternate 404 result.

Is that possible? IOW, I want to set the status code to 404 and deliver a special response page, and have the error handler middleware ignore the fact that it's a 404.

I tried setting a value in the $env and using enable_if on the middleware, but it appears the enable_if sub runs before the actual request.

Any suggestions? Thanks
