iRule for redirecting the traffic of GoogleBot to a different pool using X-Header Value

We need to redirect Google Bots traffic to another Pool, What is the effective and simple iRule I can use to accomplish that ?

We can filter the traffic using X-Header Value, which is set to value "8" are good to redirect to a new pool.

 

Does Below iRule Work ?

 

when HTTP_REQUEST { 

if { [matchclass [string tolower [HTTP::header X-forwarded-for]] equals 8] } { 

pool A 

pool default

 }

 

OR

 

when HTTP_REQUEST { 

if { [matchclass [string tolower [HTTP::header User-Agent]] contains googlebot] } { 

pool A 

pool default

 }

Hi MohanK,

when HTTP_REQUEST { if { [HTTP::header X-Forwarded-For] equals "8" && [string tolower [HTTP::header User-Agent]] contains "googlebot" } { pool A } else { pool default } }

Hello All,

 

I am looking to refine the rule proposed above just a bit and came up with the following:

---

 

when HTTP_REQUEST {

if { [HTTP::header exists X-APP-WHITELIST] and [HTTP::header X-APP-WHITELIST] equals "8" or [string tolower [HTTP::header User-Agent]] contains "googlebot" } {

pool A

else {

pool default

}

}

 

---

We are looking for the detail: "X-APP-WHITELIST" in the header equal to "8" OR if the user-agent has, "googlebot" discovered in the header. Not looking at the XFF part of the header. The, '&&' appears to be a logical AND in which both conditions have to be true. We are looking for one or the other; does not have to be both.

 

Does this look to be simpler? 

 

Thank you all for your replies.
