Hi, I'm working on link tags inside of chrome. We're now

with an optimization that uses link tags and headers to avoid round

Clarifying: essentially that's a workaround for resources for which
the actual cache information returned by HTTP GET isn't accurate,
right? Which of course leads to the question: if the maintainers of
a site can't get their cache information right, what makes you think
they can get their HTML right instead?
No, it's a performance optimization. I presume that if the link
attributes indicate that the browser's cached resource is valid, the
browser does not issue a network request to validate the resource.

So it's a workaround that causes a performance optimization. It wouldn't
be necessary if the linked resource would have the right caching
information in the first place.
So again: what makes you think they can get their HTML right instead?
Best regards, Julian
