How to access an LTM Policy variable from an iRule ?

Hi Simon,

thanks for your answer, but it still doesn't work. The irule fails with this log message:

Jul  2 07:35:09 f5-1 err tmm[20719]: 01220001:3: TCL error: /Common/syslog_https_test <HTTP_REQUEST> - can't read "policy_http_method": no such variable     while executing "log local0. "$policy_http_method""

This is the beginning of the irule (I copy/pasted the variable name to make sure it's typo free):

when HTTP_REQUEST {
    set http_method ""
    if {[HTTP::has_responded]} {
        log local0. "$policy_http_method"
        set http_method $policy_http_method
    } else {
        set http_method [HTTP::method]
    }

To explain the context:

• we have a logging irule which role is only to log traffic (you got this right Simon 😉 ) and send them to our syslog server. This irule gets [HTTP:method] and writes it to the log.
• since we upgraded from v12 to v14, the irule now fails with this error ONLY when trying to log traffic which has been matched by an LTM policy.

Jul  1 16:39:36 f5-1 err tmm2[20719]: 01220001:3: TCL error: /Common/syslog_https_test <HTTP_REQUEST> - Can't call after responding - ERR_NOT_SUPPORTED (line 14)     invoked from within "HTTP::method"

So I feel the only nice way to log this traffic is to pass the value of HTTP::method to the irule. But no luck for now 😞

OK, my bad, I found it... of course I had to put the logging policy rule on top in the policy list !

It's working now, thanks ! :)
