(2007-02-14) Scale Proxy Balancing

Jason Hoffman on getting Scalability via Proxy Server and Load Balancing. But in short, we've stayed with F5's Big Ip-s for at least one additional reason beyond their ability to handled gigabits of traffic across many many backend servers, and that additional reason is the ability to see inside packets and write iRules. iRules that can scrub http-reponse outs for credit card numbers and replace them with a "NOT ALLOWED TEXT"; iRules that can direct API traffic, bot traffic and traffic from specific user-agents to different backend pools (so you can separate API traffic from what people are hitting in a web browser), and iRules that can send .gif, .jpeg, .png off to different backend pools. All without any code changes, and this is just touching on some of the capabilities.
