Best Solution for Caching

Question

Where is the best place to implement caching in a web based app?

• At the presentation layer (hope not)?
• At the Business Logic Layer?
• At the da

Answer 1

We implement it at the business logic layer between interactions with the presentation layer. If a request from the presentation layer comes in and it is cached we can then skip a whole lot of logic and data access.

I'd highly recommend MemCached over MS Velocity, Velocity was a pain to setup!
