CORS support for CherryPy

In a nutshell

In your application, either install the tool globally.

import cherrypy_cors
cherrypy_cors.install()

Or add it to your application explicitly.

import cherrypy_cors
app = cherrypy.tree.mount(...)
app.toolboxes['cors'] = cherrypy_cors.tools

Then, enable it in your cherrypy config. For example, to enable it for all static resources.

config = {
    '/static': {
        'tools.staticdir.on': True,
        'cors.expose.on': True,
    }
}

See simple-example for a runnable example.
