Irule Integration

Hi,

your "new" irule is not working.

The condition must be:

([string tolower [HTTP::header User-Agent]] contains "msie7") or ([string tolower [HTTP::header User-Agent]] contains "msie8")

And you can optimize the irule like that:

when RULE_INIT {
    array set static::pools {
        0 "www.hector.com_cluster_2a"
        1 "www.hector.com_cluster_2b"
        2 "www.hector.com_cluster_2c"
    }
}

when HTTP_REQUEST {
    if { ([string tolower [HTTP::header User-Agent]] contains "msie7") or ([string tolower [HTTP::header User-Agent]] contains "msie8") } {
        pool www.hector.com_cluster_2k
    } elseif { [info exists static::pools([HTTP::cookie hectorlbhkg])]} {
        pool $static::pools([HTTP::cookie hectorlbhkg])
    } else {
        set PoolID [expr { int(rand()*[array size static::pools])}]
        while { [info exists static::pools($PoolID)] } {
        log local0. $PoolID
            if { ([active_members $static::pools($PoolID)] >= 3) } {
                pool $static::pools($PoolID)
                set selected $static::pools($PoolID)
                break
            } else {incr PoolID}
        }
    }
}

when HTTP_RESPONSE {
  if {[info exists selected]}{
    HTTP::cookie insert name hectorlbhkg value $selected path "/"
  }
}

The random value is an integer between 0 and the size of the static array. Adding a new entry in the array will apply without any change in the irule.
