[Help] Persistence Hash and Load Balancing together, Possible?

[Help] Persistence Hash and Load Balancing together, Possible? I know the request sounds weird... But it is true. Here is the thing: We know that F5 supplied a persistence CARP hash since 10.0.0....

The first change is good, but you need to remember the load balancing decision is only made at the start of the TCP connection after the first HTTP request. If you try to change the destination thereafter in the same connection, it will be ignored. Does that explain what you are seeing?

I do config the "onconnect" profile within the Virtual Server, and try requesting the VS by different client machine, but only 1 node access. So I don't think the issue is related to "change the destination thereafter in the same connection".
