A library to display flash messages in python web applications.
Editor: WebFlash is a library to display flash messages in Python web applications. These messages are usually used to provide feedback to the user (eg: you changes have been saved, your credit card number has been stolen, ...). One important characteristic they must provide is the ability to survive a redirect (ie: display the message in a page after being redirected from a form submission).

* WebFlash is implemented using cookies so no state must be kept in the server.
* The messages can be rendered by the browser using JavaScript. This allows pages to be cached more easily.
* The messages can alternatively be rendered by the server in the html response so JS can be disabled and still work
* The JS code is small (~1Kb) and has no dependency on any library
* The Python code is small and has no dependency outside of the standard library (if using Python 2.6, else simplejson is needed)
* WebFlash is designed to be used in WSGI frameworks with a WebOb-like Reuqest/Response objects. (only a Response object with a set_cookie(name, value) method is needed if using JavaScript? to display messages) you can free download WebFlash 1.0 now.
