There are a couple of efforts under way to define some 'standard' content for origin servers so that some at least semi-automated testing can be run against it. If you have suggestions for this please let me know. I will combine them and forward them as a single mailing on Wednesday to all who signed up. If a problem or possible issue with another participant implementation is found, that issue will be communicated to the contact for that implementation promptly. Only if the involved participants disagree on the correct behavior or if the involved participants agree to do so will the issue be brought to the working group mailing list.
Additional suggestions welcome.
