Sass support for all Plack frameworks.

Plack::Middleware::FixMissingBodyInRedirect sets body in redirect response, if it is not already set.

Plack::Middleware::ForceEnv modifies the environment passed to the application by adding your specified key value pairs. This is primarily useful when testing apps under plackup (or similar) in a development environment.

Modify HTTP response headers.

Plack::Middleware::IEnosniff is middleware for Plack. This middleware adds HTTP Header 'X-Content-Type-Options: nosniff' for safe. Sending X-Content-Type-Options response header with the value nosniff will prevent Internet Explorer from MIME-sniffing a response away from the declared content-type.

Plack::Middleware::InteractiveDebugger is a PSGI middleware component that provides an awesome JavaScript in-browser interacive debugger.

Plack::Middleware::JSConcat allows you to concatenate multiple javascripts files into one. It provides a content-hashed key as the url for including all the javascript files you specified. You can also provide a filter program to minimize the concatenated file.

Plack::Middleware::MemoryUsage is middleware for measuring process memory. Enabling Plack::Middleware::MemoryUsage causes huge performance penalty. So I HIGHLY RECOMMEND to enable this middleware only on development env or not processing every request on production using Plack::Middleware::Conditional.

Writing RESTful apps is a good thing, but if you're also trying to support web browsers, you're probably going to need some hackish workarounds. This module provides one such workaround for your Plack applications. Specifically, you can also use a header named X-HTTP-Method-Override (as used by Google for its APIs) override the POST request method. Or you can add a parameter named x-tunneled-method to your form action's query. Either way, the overriding works only via POST requests, not GET. If either of these attributes are available in a POST request, the REQUEST_METHOD key of the Plack environment hash will be replaced with its value. This allows your apps to override any HTTP method over POST. If your application needs to know that such overriding has taken place, the original method is stored under the plack.original_request_method key in the Plack environment hash. The list of methods you can specify are: GET, POST, HEAD, PUT, DELETE, OPTIONS, TRACE and CONNECT.
