What should be done to make the site work on select computers on the local network?

Question

PHP

So the question itself: there is a local network where several dozen computers are located and a local site is running. What needs to be done so that some section of this site works on specific computers, and not on the entire network?

Answer 1

read about Allow Deny in Apache config.
A small ambush, about which the docks are not.
Listing multiple ip addresses separated by commas may cause implicit use of
dns .
I was looking for the reason for the periodic friezes of my site for 5 seconds. I was looking for a long time. It turned out that after a certain number of requests, the hoster's DNS
began to respond with a delay. Why. I don't use it anywhere!
Mlyn!! Deny 1.1.1.1,2.2.2.2 (IP conditional) was to blame.

Answer 2

If you really want to pervert, then you can set up ident authentication, only you will need to install an ident server on client computers.

Answer 3

I think this is not a task of PHP in general, but of a firewall in a computer network. The options suggested here "smear" the point of filtering traffic across different hosts/applications, which, it seems to me, is erroneous.
