Redirect based on source IP address

Ranvir,

it won't work, assuming that the limited_myweb rule is used by the virtual servicing the http://limited.mywebapp.com site. Client 192.168.10.10 won't be able to connect at all.

In order to provide different response during maintenance, you may use following configuration:

pool www_servers {
    fallback "http://www.mywebapp.maintenance.com"
    member 1.1.1.1:80
    member 1.1.1.2:80
}
pool servers {
    member 1.1.1.1:*
    member 1.1.1.2:*
}
rule myweb {
    if(client_addr == 192.168.10.10) {
        use pool servers
    } else {
        use pool www_servers
    }
}
virtual www.mywebapp.com:80 {
    use rule myweb
}

In order to enter maintenance mode, you need to disable nodes in pool www_servers which triggers the fallback URL to delivered as redirect location. This is achieved using command:

bigpipe node 1.1.1.1:80 1.1.1.2:80 disable

Client 192.168.10.10 is connecting via pool servers whose members remain enabled.
