Mar 08, 2012Hi Aaron,
I guess you misunderstand me. I don't use the "event disable all" command.
I only want to share my experiences that dropping or rejecting a TCP-connection will also result in this TCL-error, when trying to insert HTTP-headers in any later iRules on the same VS.
As I mentioned, I will move our HTTP-header insert iRule at the very beginning of the VS and I expect no further issues. Regarding the "event disable all", I'm little bit afraid of using it, because there might be any negative influences for other functionalities especially when it's a default iRule, which is in place on several VS (if I remember correctly I tried this in the past and had some strange behaviors).
Ciao Stefan :)
