I found unRuleY's post (Click here)

and thought that it might be that you're making L7 changes in an event that wasn't expecting them. But then I tried the following rule in the HTTP_REQUEST_SEND event and got another error.


when HTTP_REQUEST_SEND {
HTTP::header replace Host "my_host"

Unless someone else has suggestions, I'd contact support as this looks like a bug (or two?).
