iRule error

Hello Folks,

I am working on a migration project for a customer. For some reason the iRule isn't allowing me to use "ASM::enable" event within else condition.

Following is the old and new iRules.

The old one:

ltm rule /Common/ABC-URI {
    when HTTP_CLASS_SELECTED {
        if {[IP::addr [IP::client_addr] equals 10.250.0.0/16]} {
            if { [HTTP::uri] contains "/Server/ServletSM" } {
                ASM::disable
        }
        } elseif {( [class match [IP::client_addr] equals ADMIN_Pool] )} {
            if { [HTTP::uri] contains "/sv" } {
                ASM::disable
                } 
        } elseif { [class match [string tolower [HTTP::uri]] contains CRM_CHAT_URIS] } {
                ASM::disable
                } else { ASM::enable
        }
    }
}

Here is the updated copy.

when HTTP_REQUEST {
    if {[llength [POLICY::names matched]] > 0} {
            if {[IP::addr [IP::client_addr] equals 10.250.0.0/16]} {
                if { [HTTP::uri] contains "/VGServer/VGServletSM" } {
                    ASM::disable
                }
            } elseif {( [class match [IP::client_addr] equals AD_PORTAL_SV_ECM] )} {
                if { [HTTP::uri] contains "/sv" } {
                    ASM::disable
                } 
            } elseif { [class match [string tolower [HTTP::uri]] contains CRM_CHAT_URIS] } {
                    ASM::disable
                }
           } 
           else {
            ASM::enable
  }
}

However the "else" part in the Updated iRule doesn't seem to be working. Especially "ASM::enable" event. If I change it to "ASM::disable" it works.

I am failing to understand this.

Any help?

Thank you, Darshan
