Discuss Vary header
I’m quite certain that the Vary
header is meaningless in appcache. E.g., if you wanted to serve a different page based on language, you would have to make your site’s URIs vary by language too by using domains or lang=x
query strings. If you try to use the Vary
header and your application stores server-generated pages where the server outputs different results based on Vary
, the user will only see the content as the browser accessed the website the first time.
This is my understanding/assumption, I have not actually tested for real.
