iRules fail in v14.1.2.3

I recently upgraded from v12.x to v14.1.2.3 and simple redirect/rewrite iRules seem to fail. At first I removed the iRule, deleted it and just recreated it and this worked for a bit (2nd rule below)...

Hi Zev Hi Simon,

We have the same issue with a very large and old irule using a switch.

We tried and tried but do not seem to find the correct syntax to make the irule work.

Does one if you have an example for using the HTTP::has_responded function within a switch?

(and yes we are already planning a move to using LTM policies but with multiple irules on a VS its not that easy)

Yes, Simon is correct here and I found that the 'event disable' is a critical piece! This is the only helpful answer. Literally everyone will advise to use HTTP::has_responded, even F5 LTM support and Reddit, but you must complete the pattern with event disable. Follow this syntax; I've had no more issue.
