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.
