Content Switching: Load Balancing on SteroidsLayer 7 content switching is like load balancing on steroids. It represents the most optimal way to switch requests to the most appropriate server. Click. Specific client attributes can be used. Cookie, device type, browser type, etc. can be used to forward the request.Click. Request protocols such as Gets and Posts can be used.Click. Forwarding decisions can be based on ANY payload value-we dub this deep stream inspection. Now such items as shopping cart values or platinum member passport IDs can be used to give faster service to your best customers.By matching the request with a specific server, availability is enhanced as ONLY those requests that can be serviced are forwarded; servers are not bogged down on requests they cannot fulfill. Application response time is cut as redirects are prevented. CLICK. An additional benefit is the reduction in servers needed as application replication across servers can be minimized. Servers now are specialized by application type.
