Plack::Middleware::Recursive(3pm) User Contributed Perl Documentation Plack::Middleware::Recursive(3pm) 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.
