SpyGlass is a utility for defining web content transformation proxies. Be aware that the W3C guideline is not yet fully covered. For instance, X-Device-* headers are not yet implemented. The API of this library is likely to change quite a bit before stabilizing.

The high-level goal of this project is to enable rapid development of adapter services. HTTP and caching concerns should be exposed to a minimal extent so the developer can focus on data transformation.

• Write tests!
• Provide clients with a way to retrieve fresh data
• Respect Cache-Control headers
• Web framework adapters (currently roll-your-own, except for sinatra)

Add this line to your application's Gemfile:

gem 'spy_glass'

And then execute:

$ bundle

Or install it yourself as:

$ gem install spy_glass
