Comment on latest CT Guideline Document

Hi All,

Page 7, 

1) Does Allow and Disallow lists mean Black and White lists?
2) If so, I strongly recommend to support a white lists within the CT Guidelines. We do not know owner/stakeholder of most of the websites which are "non made for mobile". So we can not expect their support.

But we can understand the customer needs and a customer could tell us that content adaptation failed e.g. due to 200ok instead of 406.

This is why I think we do need a white list. For Urls contained in that whitelist, Content adaptation shall be done in that way that a Mozilla User Agent (non mobile user agent) is setup instead of the mobile user agent.

This helps us to manage with the 406/200OK issue without buyin from the site owner.

I agree that blacklists should be ommitted. But white lists will deliver a clear advantage.

3.2.3 Control by Administrative or Other Arrangements.

The preferences of users and of servers may be ascertained by means outside the scope of this document, for example:

*	the use by transforming proxies of a disallow list of Web sites for which Content Transformation is known to diminish the user experience of content or be ineffective;

*	the use by transforming proxies of an allow list of Web sites for which Content Transformation is known to be necessary;

*	terms and conditions of service, as agreed between the user and the Content Transformation service provider.


Allow and disallow lists generally cause intractable problems for content providers since there is no mechanism for them to establish which lists they should be on, nor any generic mechanism though which they can check or change their status.
