Monitor Disables Node, persistent connections

If my monitor has marked a node as offline. Why would I want any connections persistent or otherwise to go to it?   It's down. Pick another node. How do I make this the default behavior?

Ok thanks for you help, neither reject or reset were effecting the behaviour. After a webex session with tristan from F5, we realised it was the "Receive Disable String".

According to this page: http://support.f5.com/kb/en-us/solutions/public/12000/800/sol12818.html?sr=38128338

The behaviour if the Receive String is not received, but the Receive Disable String is (in our case this was a string from an error page warning the back-end node was down) then the Node is marked UP(disabled) or "draining mode" as some people call it. The solution was to simply remove the Receive Disabled String and have the node marked as Down when the Receive String was not received.

Receive String  Receive Disable String      State
Yes                 No                               Up (Enabled)
No                  Yes                              Up (Disabled)
No                  No                               Down
