Do you have other VS on the same BIG IP?

Might be requests from EC2 match another VS?

Have you done a tcpdump to ensure you are matching the expected VS?

I have only 1 VS so it's definitely the right one matching.

However... I investigated further and realized the iRule is executing, but the "after" command is not working in these instances. I have an "after 100 <script>" line which executes on requests from my local computer (and a colleague's computer on a different network), but it doesn't execute when I send requests from some cloud VMs I tested, both on AWS and in Azure. So it's still a mystery to me..

    Sounds weird indeed.
    Could you share irule, VS config and any logs you have?
