Cherokee fix for URL prefix

Posted by Robert Vally on 2012-02-01 @ 01:17 and filed in Deployment

The snippet below is required when hosting a flask application using Cherokee+uWSGI with a prefixed URL.

class CherrokeeFix(object):

    def __init__(self, app, script_name):
        self.app = app
        self.script_name = script_name

    def __call__(self, environ, start_response):
        path = environ.get('SCRIPT_NAME', '') + environ.get('PATH_INFO', '')
        environ['SCRIPT_NAME'] = self.script_name
        environ['PATH_INFO'] = path[len(self.script_name):]
        assert path[:len(self.script_name)] == self.script_name
        return self.app(environ, start_response)

If this URL was prefixed with '/test', you would apply this to the Flask application as below:

app.wsgi_app = CherrokeeFix(app.wsgi_app, '/test')
