[Radiant] Redirect hell

[Sean Cribbs]

Thanks, John.

I guess I'll have to settle for not caching the page.  I wanted to be able
to cache the page that displayed the comments (Commentable behavior), but
have it create the child page (CommentBucket behavior, whose children are
individual comments) if it doesn't exist, and then only cache when it
exists.  Is there no way to clear the cache for that page after the redirect
occurs?

Alternatively, I'm thinking that I'm going to try redirecting to the
CommentBucket page (which already redirects back to the Commentable and is
uncached), and have it clear the cache before its redirect.  Kind of a hack,
but it just might work.
