I’m pleased to announce the initial release of Rack::Cache, a piece of  
Rack  
middleware that implements many of RFC 2616’s caching features with a  
basic  
set of storage options (disk, heap, and memcached) and a configuration  
system  
for controlling cache policy.

## Features

Rack::Cache is suitable as a quick drop-in component to enable HTTP  
caching  
for Rack-based applications that produce freshness (Expires,  
Cache-Control)  
and/or validation (Last-Modified, ETag) information.

- Standards-based (RFC 2616)
- Freshness/expiration based caching
- Validation
- Vary support
- Portable: 100% Ruby / works with any Rack-enabled framework
- Configuration language for advanced caching policies
- Disk, memcached, and heap memory storage backends

## Status

This is a young and experimental project that is likely to change  
substantially and may not be wholly functional, consistent, fast, or  
correct.  
The current focus is on reaching basic compliance with RFC 2616 and  
providing  
good documentation.

## Installation

From Gem:

```
$ gem install rack-cache

```

With a local working copy:

```
$ git clone git://github.com/rtomayko/rack-cache.git
$ cd rack-cache
$ rake package && rake install

```
