How to implement auto-refresh of the client browser page?

Question

linux

Hello!
There is a web server that is updated daily.
Clients have terminals that work through chrome.
It is necessary to implement the functionality of automatic updating of the browser page AT THE CLIENT in case an update has just been installed.
The first option is to create a daemon that will check the PID, but this is a collective farm.
How to implement smarter? It is impossible to climb into the code, it is necessary by admin methods.

Answer 1

push into html
<meta http-equiv="refresh" content="10" />

Answer 2

why?
Let me rephrase the request a bit.
I have a website, and I want all the customers who go to it - when a new product is added - their page is updated.
Do you understand that when a client contacts the site, he will read the new content anyway?

Answer 3

Without the corresponding client code - in any way. You have to write it once.
