Convert HTTP Class iRules for version 11.5.1 or later

Hey Folks,

I got stuck again with the same issue, this time the iRule is a little complex than the one I asked earlier.

Following is the snippet for your reference.

when HTTP_REQUEST {

       set FLAG_BLOCKED 0
       set Disabl_ASM_FLAG 0   
        if {$GLOBAL_breakALL == 0}
    {   
       if {[HTTP::uri] starts_with "/admin/content/"} {
    if {[class match [IP::client_addr] equals AB_Web_Folder_IP]}  { 
     log local0. "Access to admin is allowed"
        ASM::disable    
         set Disabl_ASM_FLAG 1
    } else {
       log local0. "Someone trying to access /admin/content/ illegally from Source IP: [IP::client_addr] "
        set FLAG_BLOCKED 1
        set Disabl_ASM_FLAG 1
    }
    }
}
}
when HTTP_CLASS_SELECTED
{
log local0. "inside class selection"
    if {$Disabl_ASM_FLAG == 1}
    {
        if { [HTTP::class asm] == 1 }
        {
            ASM::disable
                       log local0. "ASM is disabled now"
        }
    }
    if {$FLAG_BLOCKED == 1}
    {
        reject
    }
}

How can I eliminate the use of when

HTTP_CLASS_SELECTED

HTTP::class ASM

Thank you,
