I'm trying to write an irule with multiple not scripts in it

Hi,

you can try to use array to define old and new hostnames:

when RULE_INIT {
    array set static::NewURL {
        m3.companyname              a1.m3.companyname
        internal.m3.companyname     internal.a1.m3.companyname
        internal.m3-dc1.companyname internal.a1.m3-dc1.companyname
        internal.m3-dc2.companyname internal.a1.m3-dc2.companyname
        internal.m3-dc3.companyname internal.a1.m3-dc3.companyname
    }
}


when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::path]] {
        "/abcd/web/abcdpayment.web/*" -
        "/abcd/web/abcdpaymentprocessing.web/*" {}
        "/abcd/*" {
            if {[info exists static::NewURL([HTTP::host])]} {HTTP::redirect http://$static::NewURL([HTTP::host])[string tolower [HTTP::uri]]}
        }
    }
}
