I think the following should work for you:

when HTTP_REQUEST {
    set selectedPool [LB::server pool]
    set lowerHost [string tolower [HTTP::host]]
    set lowerPath [string tolower [HTTP::path]]

    if {$lowerHost ends_with "auction.com"} {
        set clientIP [getfield [IP::client_addr] "%" 1]
        if {($lowerPath starts_with "/test/admin") && !(([IP::addr $clientIP equals 10.10.10.0/24]) || ([IP::addr $clientIP equals 20.20.20.0/24]))} {
            reject
        }
        set selectedPool Auction-Pool

    } elseif {$lowerHost ends_with "test.com"} {
        set selectedPool test-Pool
    }
    pool $selectedPool
}
