ACE stickyness, is cookie cleared when server is down?

Hi people,

I am using stickyness with cookies, and I have server01 cookie for server1 and server02 cookie for server2.

What happens when the server2 goes, but the client has already set cookie server02.

Will ACE continue to send it to server2 untl the cookie timeouts? or will it send to the client a new cookie (server01)?

any help greatly appreciated,

George

Re: ACE stickyness, is cookie cleared when server is down?

When a request comes in with a cookie, ACE will find the associated server.

Then it does check if the server is available.  If yes, traffic is forwarded to that server.

If not, a regular lodbalancing decision is made and another server is selected.

Traffic is forwarded to that server and a new cookie is sent to the client so that it should now stick to that server.

Gilles.
