*What is Stateful & Stateless Persistence? Which one is more scalable/Efficient?

Stateless Session Persistence: Cookie inserted by ADC is more efficient because no need to create a table, NS will insert cookie & forget, with reply, it will read cookie value, decrypt it & fwd request.

State-full Session Persistence: Server will insert cookie, NS will hash it & fwd based on Hash value but will need to keep a table in memory with all hashes & IP Addresses.

Same is true for Source IP based Persistence, Also inefficient behind NAT

Using Set-cookie-header = by Server - insert Name & Value Fields

Client sends cookie in Cookie Header

Who ever generates cookie, will be able to read it
