Increasing Control With Property Manager 17
bcef2e6f0ed504b8dc9d6033346c0e13&f=myfunc
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

18. Caching Dynamic Responses

However our domain is used to do lots of things: images, JSON, etc.
We want to cache JSON 5 mins and images 45 days”
