Comment 8 for bug 607961

If we serve WADL from Apache then it will only change when the web service actually changes (since Apache generates ETags based on the content of a file). As long as we don't put any revision number in the WADL (I don't think we do) we'll be fine. The ETag generated by lazr.restful changes at every rollout because it's based on the revision number.

This is not really the place to discuss such a thing, but what are you thinking of replacing WADL with? We could probably use HTML5 + URI Templates.
