NAME

       Plack::Middleware::ContentLength - Adds Content-Length header automatically

SYNOPSIS

         # in app.psgi

         builder {
             enable "Plack::Middleware::ContentLength";
             $app;
         }

         # Or in Plack::Handler::*
         $app = Plack::Middleware::ContentLength->wrap($app);

DESCRIPTION

       Plack::Middleware::ContentLength is a middleware that automatically adds "Content-Length"
       header when it's appropriate i.e. the response has a content body with calculable size
       (array of chunks or a real filehandle).

       This middleware can also be used as a library from PSGI server implementations to
       automatically set "Content-Length" rather than in the end user level.
