flash scope issues in grails when cookies are disabled

In my application I want to have some dynamic content av开发者_运维问答ailable to search engine bots which have cookies disabled. But I am stuck because I need to pass redirect URL via flash scope to redirect to different action and controller. When I use chain instead of redirect then I am able to get flash scope data but I have some use cases in which I cannot use chain and have to use redirect this is also because chain (uri: '/') does not work correctly as this will redirect to index action of current controller and not to the controller that is defined for root '/'. The issue is that flash scope loses everything when cookies are disabled and doing redirect instead of chain. Is this a bug in grails or know limitation in grails?

When cookies are disabled I still see URL being rewritten with ;jessionid=some_value but according to documentation by default url would not be rewritten with jessionid. When cookies are enabled then url is not rewritten as expected. Is this a bug in grails or expected behavior? How do I disable URL rewriting in grails when cookies disabled?

I also understand that the implication of disabling cookies and URL rewriting is that each request would result in new session object creation.

Not sure if it is the solution you are looking for, but have you tried Marc Palmer's One-Time Data plugin?
