AJAX - Security - keep your logic on the server!

Eric Pascarello gives some good points to think of, before we 'digg' to deep in the AJAX mania. Priorities for Online Apps: 1. Security! 2. Performance 3. funny gadgets should keep users returning daily day But please not at the cost of security or performance.

"Now speed of execution is also a point that was brought up. Your server running server side code should be a lot faster than most people's computers running JavaScript. Get a person with 10 browser windows open, word and excel, acrobat reader, outlook, media player, and those spyware apps running and say bye to the memory and speed. Ever run a for loop with 3000 interactions? Some people's browsers choke and freeze up. This is one main reason to stick with the server for business logic is more reliability in processing information. Plus most servers are built to crunch data. Why use a browser running JavaScript that has poor memory management (unless you built your server side app. with poor memory management, but that is a different story!) "
