Sanal_Babu Assuming the default pool that you would like to forward traffic to is associated to this virtual server the following iRule should do what you are looking for.

when CLIENT_ACCEPTED priority 500 {

    set DEFAULT_POOL [LB::server pool]

}

when HTTP_REQUEST priority 500 {

    set URI [string tolower [HTTP::uri]]

    switch -- ${URI} {
        /en/services/ -
        /en/ajax/logout -
        /en/e-service-errors {
            pool ${DEFAULT_POOL}
        }
        default {
            HTTP::redirect "https://stg.bbbb.com"
        }
    }

}
