NimbostratusOccasional TCL Errors for HTTP::method ?
We use the following at the top of our main HTTP iRules:
-------------------
when RULE_INIT {
set sec_http_versions [list "0.9" "1.0" "1.1" ]
set sec_http_methods [list "GET" "POST" "HEAD"]
}
when HTTP_REQUEST {
if { ![matchclass [HTTP::version] equals $::sec_http_versions ] } {
reject
}
if { ![matchclass [HTTP::method] equals $::sec_http_methods] } {
reject
}
(rest of the iRule goes here)
}
--------------------
I'm pretty sure we snagged that from an F5 DevCentral newsletter awhile back.
Anyway, recently, we have started getting the following messages sporadically in the TMM logs:
=====================
Oct 16 01:01:30 tmm tmm[1120]: 01220001:3: TCL error: Rule poolpicker - Not found. Invalid server side API (line 1) invoked from within "HTTP::method"
Oct 16 07:35:31 tmm tmm[1120]: 01220001:3: TCL error: Rule poolpicker - while executing "HTTP::method"
Oct 16 12:30:50 tmm tmm[1120]: 01220001:3: TCL error: Rule poolpicker - while executing "HTTP::method"
=====================
Does anyone know what causes these errors? My best guess is corrupted packets, but the error is so generic I have no way to verify that. I couldn't find much in the AskF5 KnowledgeBase either.
Thanks in advance,
Chip
rayden_75606I played around with your irule a little and had a little success with the following:
though I generally set this at the command prompt
example: bigpipe class valid_methods { \"CONNECT\" \"GET\" \"POST\" \"HEAD\" \"OPTIONS\" }
then set my call to it anywhere not needed to init in rule, but this is with your init in the rule
when RULE_INIT {
set sec_http_versions [ "0.9" "1.0" "1.1" ]
set sec_http_methods [ "GET" "POST" "HEAD"]
}
when HTTP_REQUEST {
if { not [matchclass [HTTP::version] equals $::sec_http_versions ] } {
reject
} elseif { not [matchclass [string toupper [HTTP::method]] equals $::sec_http_methods] } {
reject
}
