Upgrade notes from Apache to Plack version
Should use "use Moose; extends 'Combust::Control';" instead of just "use base 'Combust::Control'"
The Apache configuration template gets a 'plack' variable set to true when the configuration is built for plack.
request->cookie for "plain" cookies is deprecated; use request->(response->)cookies instead (see Plack::Response for details).
request->uri now returns a URI object with some extra code to have it emulate the old behavior of just returning the path when stringified.
There's no more Combust::Control::Error module
proxyip_forwarders are not "chained"; only the most recent header is read. Plack::Middleware::ReverseProxy would have to be changed to fix that.
When using proxyip_forwarders, X-Forwarded-Server, X-Forwarded-Host, X-Forwarded-Port, X-Forwarded-HTTPS and X-Forwarded-Proto headers are also supported.
