Business Need #2: Cache A Dynamic Response
Increasing Control With Property Manager 16
How can we improve performance of a dynamic object like an ad package, shopping cart, etc. via caching?
Caching Dynamic Responses

What It Does
• Creates a unique object for the session that is part of the transaction, ad, or shopping experience
• Linked to a specific cookie
• The response object is able to change if the application changes the query string variables c, m, or f
Business Goal
• Reduce origin database load
• Improve performance for end-user

Business Need #4: Caching 100% Dynamic Things With NO CERTAIN URL
Increasing Control With Property Manager 26
“Image URL? We are no longer so primitive. We are 100% dynamic, there is no image URL, our images come from an algorithm, there is no path.
However our domain is used to do lots of things: images, JSON, etc.
We want to cache JSON 5 mins and images 45 days”
