How to distribute the load on several servers, and so that the pictures are loaded only from 1?

Question

Highload

How can I organize the following:
There is 1 domain and 2 web servers (apache). It is necessary that the main page opens either on server 1 or on server 2, and all other pages and pictures on server 1.
1. Can this be implemented at the DNS level?
2. If not, then how to do it?

Answer 1

1. No
2. Install a more or less "smart" balancer, for example lighttpd
For example, we have server 1: ip AAAA
server 2: ip BBBB
domain: vasya.ru
Then on server 1 we hang Apache on 127.0.0.1 port 8080
Listen 127.0.0.1 :8080
Install lighttpd, then in lighttpd config:
server.bind = "AAAA" # Attach lighttpd to external IP
# Enable proxy module
server.modules = (
"mod_proxy"
}
$HTTP["host"] =~ "vasya\.ru " {
setenv.add-request-header ( "Host" => "vasya.ru" ) # add HTTP header
proxy.balance = "round-robin"
proxy.server = ( "(?!index\.php)" = >(( "host" => "127.0.0.1", "port" => 8080 ),
( "host" => "BBBB", "port" => 80)),
"\.(gif|jpg|png|ico)$" => (( "host" => "127.0.0.1", "port " => 8080 )),
"" => (( "host" => "127.0.0.1", "port" => 8080 ))
)
}
Something like this. But it is not at all clear why such a perversion is needed.
