RE: [PageVisibility]

Carter,

Unfortunately, this model would appear contrary to the current web platform conventions. On the client, one can check the existence of document.hidden to determine if this feature is supported. 

Thanks,
Jatinder

Hello,

I would like to strongly suggest that browsers implementing the Page Visibility guidelines identify themselves by using a X-Page-Visibility (or
similar) header. This would give webmasters the ability to utilize the suggestions put forth in the Page Visibility guidelines with increased efficiency. It also would give them the ability to block such requests as desired.

Suggested attribute and possible values:

X_PAGE_VISIBILITY: (hidden|visible|preview|prerender)

Thank you,
