hi. i have pool of sharepoint front end server and another pool of web farm servers. I am using windows NLB and on another location (netscaler) I am interested in branch cache that comes with Win 2008 R2 and i want to ask : in an NLB scenario, how can i make sure that the Server Secrete that is used to generate segment hashes of data, i identical on all web farm nodes, to get max optimization? To explain more : Branch cache will divide the data to blocks and segments and will hash the segment. In order to protect from brute attack , the algorithm will hash the resultant segment hash + a server secret. So if i have 10 IIS nodes in NLB senario, the same data segment will have different hashes on each node. So clients using branch cache will almost always see different cache values and will not benifit from branch cache. Any help?ammarhasayen
