NAME

       Plack::Middleware::Recursive - Allows PSGI apps to include or forward requests recursively

SYNOPSIS

	 # with Builder
	 enable "Recursive";

	 # in apps
	 my $res = $env->{'plack.recursive.include'}->("/new_path");

	 # Or, use exceptions
	 my $app = sub {
	     # ...
	     Plack::Recursive::ForwardRequest->throw("/new_path");
	 };

DESCRIPTION

       Plack::Middleware::Recursive allows PSGI applications to recursively include or forward requests to other paths. Applications can make use
       of callbacks stored in "$env->{'plack.recursive.include'}" to include another path to get the response (whether it's an array ref or a code
       ref depending on your application), or throw an exception Plack::Recursive::ForwardRequest anywhere in the code to forward the current
       request (i.e. abort the current and redo the request).

EXCEPTIONS

       This middleware passes through unknown exceptions to the outside middleware stack, so if you use this middleware with other exception
       handlers such as Plack::Middleware::StackTrace or Plack::Middleware::HTTPExceptions, be sure to wrap this so Plack::Middleware::Recursive
       gets as inner as possible.
