SACK is a simple JavaScript library that provides AJAX communication support. Its focus is on ease of use and simplicity. Requests are made by creating a single object, which contains support for URL encoding data. There is no direct support for RPC or JSON, but the library is simple enough that it would be easy to extend. Support for managing errors is minimal, but loading notification is provided by adding event-handling functions.
