No, we still can't do that. We have to implement a mechanism to extract parts of requests and reuse them at other places (basically session-based variables) but there's nothing yet. It's in the roadmap though. You'll have to find another way to do it unfortunately. If you have just a few domains, you can write a few rules (one per domain) to perform conditional rewrites (eg: if Host matches XX, rewrite URI as /domains/XX/original-uri). If you have too many of them, you'd better look at another product for the job. I think that nginx is particularly suited at these tasks. Regards, Willy
