BIGIP LTM Loadbalancing for Cache Farm with Client IP Spoofing feature.

Dear all.

 

 

Finally, I got support from F5 Technical and we have to use iRule.

 

I post this iRule here for reference.

 

 

when HTTP_REQUEST {

 

set High_Score -9999999999

 

set Node_Picked “”

 

set Pool_Picked pool_[expr {crc32 [HTTP::uri]} % 10]

 

foreach Cur_Node [active_members -list $Pool_Picked] {

 

if { [crc32 $Cur_Node[HTTP::uri]] > $High_Score } {

 

set High_Score [crc32 $Cur_Node[HTTP::uri]]

 

set Node_Picked $Cur_Node

 

}

 

}

 

pool $Pool_Picked member [lindex $Node_Picked 0] [lindex

 

$Node_Picked 1]

 

}

 

 

Note that this iRule requires version 9.4.2+. Change to

 

your pool name.
