Tom Real good articles on NLB! We have been working on lot of issues regarding NLB, affinity and SSL. We have a scenario where we are testing SSL with no affinity(not recommended though) as every request will go through SSL handshake process. Do you know how much overhead will be there if we use the above mentioned scenario.Thanks Shobha Pandey Network Operating Systems OIS Bureau of Technology Department of Public Welfare 717 772 7204
