Hello, Bear with me if this has been answered elsewhere, I've found threads that seem similar but nothing exactly like what I'm trying to do and none of the related examples seem to work. I'm tryin...
Hi randyrue,
If you have more than one iRule on a VIP dealing with HTTP::respond it is important to manage the execution using various commands. If the HTTP::respond fires then there are a limited amount of "HTTP" commands that you can use, otherwise you will recieve a TCL error. One of the methods of guarding against that is to check the HTTP::has_responded command in your code: https://clouddocs.f5.com/api/irules/HTTP__has_responded.html
You could check your LTM logs for messages like this:
01220001:3: TCL error: /Common/<iRule_name> <HTTP_REQUEST> - ERR_NOT_SUPPORTED (line 1)     invoked from within "HTTP::host"
A good breakdown of the issue and solutions is here: https://support.f5.com/csp/article/K23237429
In a nutshell, adding the code "if { [HTTP::has_responded] } { return };" to the beginning of your iRules after the when HTTP_REQUEST command should help.
Best,
Josh
