Plack::Middleware::RearrangeHeaders - Reorder HTTP headers for buggy clients
SYNOPSIS
use Plack::Builder;
my $app = sub {
return [ 200, [
'Last-Modified' => 'Wed, 23 Sep 2009 13:36:33 GMT',
'Content-Type' => 'text/plain',
'ETag' => 'foo bar',
], [ 'Hello Foo' ] ];
};
builder {
enable "Plack::Middleware::RearrangeHeaders";
$app;
};
DESCRIPTION
Plack::Middleware::RearrangeHeaders sorts HTTP headers based on "Good Practice" i.e.:
# "Good Practice" order of HTTP message headers:
# - Response-Headers
# - Entity-Headers
to work around buggy clients like very old MSIE or broken HTTP proxy servers. Most clients today don't (and shouldn't) care about HTTP
header order but if you're too pedantic or have some environments where you need to deal with buggy clients like above, this might be
useful.

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.
