html - Is it possible to make server push without using javascript? -

-

is there mechanism provide server push technology using plain html, without using javascript (or other script languages on client side).

under "server push" mean process server update part of page content when needed.

i don't know of way true server push can used without javascript in page.

without javascript, thing i'm aware of meta refresh tag tell browser refresh page after particular time interval. tag applies whole page only. if wanted part of page updated, use iframe , have iframe updated. of course, not server push, client-driven auto-update , run on predetermined interval, not when there new data. smarter this, need javascript.

the efficient server-push use javascript page connect server on websocket , have server send data page via websocket whenever wants (true server-push). client's javascript can respond receipt of websocket data updating particular piece of page.
