NimbostratusHTTP::class select problem
Hi All,
I'm using LTM 6400 with WA module, following is my configuration.
------------------------------------
HTTP CLASS - total 4 HTTP classes
------------------------------------
profile httpclass ist_class {
defaults from httpclass
pool ist_pool
redirect none
wa disable
hosts none
paths
"/Testfile/*"
"/IST/*"
headers none
cookies none
}
profile httpclass equery_class {
defaults from httpclass
pool menara_web
redirect none
wa disable
hosts none
paths "/eQuery/*"
headers none
cookies none
}
profile httpclass cn_https_class {
defaults from httpclass
pool https_pool
redirect none
wa enable
hosts none
paths none
headers none
cookies none
}
profile httpclass ost_class {
defaults from httpclass
pool ost_pool
redirect none
wa disable
hosts none
paths "/OST/*"
headers none
cookies none
}
-----------------------------
virtual server configuration
-----------------------------
virtual Maybank2u_vs {
translate service disable
destination 20.134.32.196:https
ip protocol tcp
rules m2u_irule
httpclass ist_class equery_class ost_class cn_https_class
profiles
Maybank2u_clientssl
http_custom
internal_serverssl
tcp
}
--------------------------------
because of application behavior i need to used irule to do redirection as well as persistence, following is my irule setting
------------------------------------------
rule m2u_https_irule {
when HTTP_REQUEST {
if { [HTTP::uri] starts_with "/TestFiles/" } {
persist source_addr timeout 300
HTTP::class select ist_class
}
elseif {[HTTP::uri] starts_with "/IST/" } {
persist source_addr timeout 300
HTTP::class select ist_class
}
elseif {[HTTP::uri] starts_with "/eQuery/" } {
persist source_addr 300
HTTP::class select equery_class
}
elseif { [HTTP::uri] starts_with "/OST/" } {
persist source_addr timeout 1800
HTTP::class select ost_class
}
else { HTTP::class select cn_https_class }
}
}
-------------------------------------------
i get this error message from the log file
"Aug 25 00:03:43 tmm tmm[1538]: 01220001:3: TCL error: Rule cn_https_irule - Illegal argument (line 17) invoked from within "HTTP::class select ost_class"
-----------------------------------------------
anyone have any idea what this error message means?
appreciate if you can give me some suggestion on how to fine tune this rule.
thanks in advance.

kykong_107132i think i know the reason why i have that error messages. they remove few httpclass from virtual server.

As you found, the HTTP class you select needs to be configured on the virtual server...
SOL6826 (Click here)
The connection fails under these circumstances because, unlike pools, HTTP classes are not a global resource. HTTP classes must be assigned to the virtual server in order for the virtual server, or an iRule that is assigned to the virtual server, is allowed to use the HTTP class.
