Plack::Middleware::RecUservContributed Perl DocPlack::Middleware::Recursive(3)NAMEPlack::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 $app = sub {
# ...
Plack::Recursive::ForwardRequest->throw("/new_path");
};
DESCRIPTIONPlack::Middleware::Recursive allows PSGI applications to recursively
include or forward requests to other paths. Applications can make use
of callbacks stored in "$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.
