Hi,

 

don't change static variables in HTTP_REQUEST event... static variables are variables shared by all TMM

 

static variables may be set in RULE_INIT (when irule is loaded : restart of appliance or code change)

 

when RULE_INIT {
    set static::maxRate 8
    set static::timeout 600
}

then use the variable in HTTP_REQUEST.
