Plack::Middleware::Recursive - Allows PSGI apps to include or forward requests recursively
# 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"); };
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).
$env->{'plack.recursive.include'}
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.
