I assumed there would simply be a Storage in the response object I could just stuff things into, but it seems not. So my question is what's the easiest way to append POST data to a response (for both cases: a redirect and a non-redirect)?
Maybe I'm going about this the wrong way. I have a simple 'bad request' error page which I'd like to redirect to when the URL is no good, e.g. a bad id passed as an arg. I'd like to pass a message to this error page, e.g. 'No such post.', but I'd rather that text not show up in the URL, so I'd like to pass it as POST data.
