Reverse Proxy Setup

Hi,

I made an example to do this trick based on the server IP address.

To do it with node's name, I think you must create a data group with servers name as values and IP as key then check it in switch statement.

You must associate a stream profile in the VS.

Regards.

when CLIENT_ACCEPTED {
     ensures the server informations to the HTTP_REQUEST event.
    LB::connect
}

when HTTP_REQUEST {
     stores the current host header value
    set request_host "[HTTP::header Host]"

     checks the member by address:port
    switch "[LB::server addr]:[LB::server port]" {
        "10.10.10.1:80" {
            set rewrite_host "aa1.foxrun.com"
        }
        "10.10.10.2:80" {
            set rewrite_host "aa2.foxrun.com"
        }
        "10.10.10.3:80" {
            set rewrite_host "aa3.foxrun.com"
        }
        default {
            set rewrite_host ""
        }
    }

     If found, change their request.
    if { $rewrite_host ne "" } {
        STREAM::disable
        HTTP::header remove "Accept-Encoding"
        HTTP::header replace "Host" $rewrite_host
    }
}

when HTTP_RESPONSE {
    if { [HTTP::header value "Content-Type"] contains "html" and $rewrite_host ne "" } {
         replaces the content with the previous request host header
        STREAM::expression "@$rewrite_host@$request_host@"
        STREAM::enable
    }
}
