Hi.

 

Thanks a lot for your responses.

 

We can´t ditch the irule because we need it to maintain HTTP-to-HTTPS persistece. Built-in persistence doesn´t implement match across services option, that is the reason we use this irule.

 

Our monitor is not aggresive. It is an HTTP monitor testing in 15 sec. steps

 

Action on service down option is configured with default value none. Perhaps we had to try with Reselect, Am I wrong??

 

Thanks

What aFanen01 is trying to say is it does not matter if you call the site using http or https it will persist across services naturally so the iRule is not required. Cookie persistence is independent of protocol in this case. HTTP or HTTPS does not matter, as long as the destination uses the same pool name then the built in cookie persistence will do what you want.
