iRule - Is it possible to select a different pool and do an http redirect without infinite loop?

Hi, you might be using an improper event for this purpose.

  when HTTP_REQUEST {
    if { [active_members [LB::server pool]] < 1 } {
        if { [string tolower [URI::decode [HTTP::uri]]] starts_with "/ohrcc/pages/client" } {
            log local0. "iRule:client-maintenance - routing to maintenance pool"
            Use this
            use pool client-maint
            Or
            HTTP::respond 302 Location "https://client.accenture.com/test/maintenance-page.htm"
        }
        elseif { [string tolower [URI::decode [HTTP::uri]]] starts_with "/placeholder-check-for-future-maintenance-pages" } {
            log local0. "iRule:future-maintenance - routing to maintenance pool"
            use pool future-maint
        } else {
            log local0. "iRule:Lantmannen-maintenance - routing to normal pool"
            use pool normal-pool
        }
    }
}

when LB_FAILED {
    persist none
    LB::reselect
}
