CirrusWhat's the diff between Match Across Virtual Servers and Match Across Pools?
Hi there, i m looking at this link: https://support.f5.com/csp/article/K5837. And I still don't get the difference between Match Across Virtual Servers and Match Across Pools. Don't they both end up pointing to the same node? Can someone help me understand? Thanks!

The behaviour is quite different:
Match across services ensures that a client that has a connection via one port to a pool member will connect to that same pool member with a new connection on a different port.
client --> https virtual --> pool member 1
client --> http virtual --> pool member 1 match across services
Match across pools is used on a virtual that may direct content to multiple pools based on a policy/irule. The persistence record matches on the client ip address and sends to the pool and member regardless of the irule:
client --> http virtual "/url1" --> pool_1
client --> http virtual "/url2" --> pool_2
.........
client1 --> http virtual "/url1" --> pool_1 node 1
client2 --> http virtual "/url2" --> pool_2 node 1
client1 --> http virtual "/url2" --> pool_1 node 1 match across pools
client2 --> http virtual "/url1" --> pool_2 node 1 match across pools
I hope this is clear.
