Un-Answered Questions { C Sharp }

These questions were asked me in a technical interview: •If we deploy an application on multiple server (like database server, web server) then, each request should be redirected to proper server, then how you will handle it in your code? •How security pinholes will be handled in an application? •What things should be considered while writing a web application? •How will you do load/performance testing of web application? Which framework you will use for it? •How will you implement a cache for results which require a DB access? Please let me know how to write an web application considering all these points. I am not so much aware of architechural design of web application. Your guidelines will be helpful.
