At what point is the reset sent to the client? Would this be during a persistent existing connection where a server is marked down and the next packet from the client is reset by ax at that time?
or, is this only so narrow as to the initial lb selection of server? ex: tcp vip, client sends syn, ax opens connection to server, at that time server fails during handshake, but AFTER selection.
what is the exact sequence of events where this setting occurs?

By default once a TCP is established on a VIP, AX will send a RST or FIN to the client only and only if the server sends such packet.
Now this behavior can be changed.
With the option "reset-rev" under "tcp template", you can ask AX to send a RST to the client when:
. the session expires
. the server is detected down
FYI there is a similar option "reset-fwd" under "tcp template", to ask AX to send a RST to the server when:
. the session expires
Note: Don't forget to associate that tcp template to your VIP to get it applied
