Is any CDN honor the "stale-while-revalidate" http header?

    Hi there,

    Few days ago, I asked about "stale-while-revalidate" question but nobody answered it. So, I think I need change my question:

    Anyone know if any CDN honor the "stale-while-revalidate" http header,
    for example a header looks like:
    Cache-control => max-age=10800, public, stale-while-revalidate=21600, stale-if-error=43200
    Code (markup):
    (These new headers describe at http://tools.ietf.org/html/rfc5861 )
    SEMrush
    If a CDN honor these headers, it should work like this:
    the page which gives this header, will be stored for 10800+43200 seconds, within the first 10800 seconds, the cached version will be served. After 10800 seconds and before 21600 seconds, a staled cached version will be served and a request for updates will be sent to original server in background.

    I wanna know if any CDN honor and implemented these headers include stale-while-revalidate and stale-if-error. If not, do anyone know any CDN has a plan to have it?

    Got a letter back from Akamai:

    Question: If Akamai CDN honor and implement headers stale-while-revalidate and stale-if-error which are included in cache control header?
    Answer: As these headers were recently published (May 2010), as of now, we don't honor these headers.

    Q: Do we have a plan to have it?
    A: As of now, we do not have any time frame.

    I also contact more (almost all of them) CDN providers, none give positive answer. Except internap. I will update this thread when I have more news
