That's right. I copied the iRule from the post and made the suggested change.

 

 

iRule runs w/o problems until I create a 500 on the server (ColdFusion restart), at which point I get the error in the browser (redirecting in a way that will never complete).

 

 

Looks like it keeps selecting the same node.

 

 

BTW, we're on 9.4.3 Build 1.4 Final.
