DESCRIPTION
    This is a refactoring/stealing of Catalyst's useful debugging output for
    use in any Plack application, sitting infront of a web framework or
    otherwise. This is ideal for development environments. You probably
    would not want to run this on your production application.

    This middleware will use psgix.logger if available in the environment,
    otherwise it will fall back to printing to stderr.

    There are a large list of attrs which can be used to control which
    output you want to see:

    debug
    request
    response
    request_headers
    request_parameters
    response_headers
    response_status_line
    keywords
    uploads
    body_params
    query_params

NAME
    Plack::Middleware::DebugLogging - Catalyst style console debugging for
    plack apps

METHODS
  $self->log_request
    Writes information about the request to the debug logs. This includes:

    *   Request method, path, and remote IP address

    *   Query keywords (see "query_keywords" in Catalyst::Request)

    *   Request parameters

    *   File uploads

  $self->log_response
    Writes information about the response to the debug logs by calling
    "$self->log_response_status_line" and "$self->log_response_headers".

  $self->log_response_status_line($response)
    Writes one line of information about the response to the debug logs.
    This includes:

    *   Response status code

    *   Content-Type header (if present)

    *   Content-Length header (if present)

  $self->log_request_parameters( query => {}, body => {} )
    Logs request parameters to debug logs

  $self->log_request_uploads
    Logs file uploads included in the request to the debug logs. The
    parameter name, filename, file type, and file size are all included in
    the debug logs.

  $self->log_headers($type => $headers)
    Logs HTTP::Headers (either request or response) to the debug logs.
