Sticky with 404 on CSS11501

we have HTTP redirect and SSL termination configured at CSS11501.

we are using server generated Cookie for session stickiness, one issue we found is that: within one HTTP1.1 request, there might be some objects missing (like some images), then the session is switched to the next available server, and the user would see the pop-up window asking for re-authentication.

And I am just using ICMP for keepalive (which means the servers / services would be always UP), but it still does not help, my thought is that my session would be stuck on one particular server based on the cookie, and I would expect to see some "x" in the web page, but my session should stick on one server?

Re: Sticky with 404 on CSS11501

the CSS does not have the possibility to dynamically learn cookie.

So, you have to setup manually the value sent by each server.

According to your setup, the jsessionid would have a fix value after the first 33 bytes and the value will be 2 bytes long.

Is that correct ?

If yes, try to increase the string range.

Finally, it might be easier to use arrowpoint cookies.
