HSL in LTM to replicate tcp packets to multiple pools

Hello - We are actually trying to leverage HSL to replicate tcp traffic coming on to one pool to another one.This is the iRule. its connecting to both the pools but the data is not been send using the HSL::send command.

 

Could you please suggest what we are doing wrong here ?

 

 

when CLIENT_ACCEPTED {

 

set hsl [HSL::open -proto TCP-pool test1-57590]

 

TCP::collect

 

}

 

 

when CLIENT_DATA {

 

HSL::send $hsl TCP::payload

 

pool test2-57580

 

TCP::release

 

}
