Trying to add more restrictions to exiting iRule with flags

Try something like below. It should be less complicated and more efficient.

when HTTP_REQUEST { if { [HTTP::host] starts_with "foo.com" } {
    If URI start with /gel/ or /water/ validate allowed IP and send it to the pool or redirect
    if { [HTTP::uri] starts_with "/gel/" || [HTTP::uri] equals "/water/" } {
        if { [class match [IP::client_addr] equals allow_address_data_group ] } {
            pool secure_80_pool
        }
        else {
            HTTP::redirect "http://deafult-internal.net"
        }
    }
    If URI start with /new-URIr/ validate allowed IP and send it to the pool or redirect
    elseif { [HTTP::uri] starts_with "/new-URI/" } {
        if { [class match [IP::client_addr] equals new_allow_address_data_group ] } {
            pool secure_80_pool
        }
        else {
            HTTP::redirect "http://deafult-internal.net"
        }
    }
    Redirect all other URI
    else {
        HTTP::redirect "http://www.default-external"
    }
}
