I did manually edit resin.xml for one of my webapps to respond to comics.stage.roderickmann.org, and created a DNS entry to match. But it can be tedious to change them all (not too bad, really, just looking for a nicer way). Eventually, all the stage nonesense will go away and the new machine will completely replace the old and the old will go away. -- Rick ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest === Paul Cowan, Software Engineer Caucho Technology co...@caucho.com http://blog.caucho.com http://twitter.com/cauchoresin ___ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest

Re: [Resin-interest] Rewriting hostnames across webapps?
Wouldn't adding (stage\.)? to each host-alias-regexp and changing the host-name to regexp allow it to work as you want it?

Re: [Resin-interest] Rewriting hostnames across webapps?
Yep, I think it would. The problem is, what if I want a more complex transformation next time? Or just a different string other than stage inserted? It's okay, this works well enough for me now.
