Reverse proxy Authentication

[senthil kumar <senthilkumaar2021@xxxxxxxxx>]

Hello Team,

I have configured reverse proxy in squid with 3 cache_peers and
enabled basic authentication.

When i visit each sub domain the authentication prompt appears , i
need to get authenticated only one, is it possible?

Cache peer1-  test1.example.com
Cache peer2-  test2.example.com
Cachepeer3-   test3.example.com

Thanks,
Senthil
