NAME ^

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.
