NAME

6       Plack::Middleware::Recursive - Allows PSGI apps to include or forward
7       requests recursively
8

SYNOPSIS

10         # with Builder
11         enable "Recursive";
12
13         # in apps
14         my $res = $env->{'plack.recursive.include'}->("/new_path");
15
16         # Or, use exceptions
17         my $app = sub {
18             # ...
19             Plack::Recursive::ForwardRequest->throw("/new_path");
20         };
21

DESCRIPTION

23       Plack::Middleware::Recursive allows PSGI applications to recursively
24       include or forward requests to other paths. Applications can make use
25       of callbacks stored in "$env->{'plack.recursive.include'}" to include
26       another path to get the response (whether it's an array ref or a code
27       ref depending on your application), or throw an exception
28       Plack::Recursive::ForwardRequest anywhere in the code to forward the
29       current request (i.e. abort the current and redo the request).
30

EXCEPTIONS

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