How to log only the first connection from a client to a source address perstence enabled virtual server ?

If I have virtual server that has source address persistence enabled, is there a way I can log the client address connecting to it ONLY for the first time and NOT its subsequent connections ?

The example in the Wiki link shows using the HTTP_REQUEST, for which there will be a need to enable HTTP profile to the virtual server first. Can the HSL be enabled something like below -

 

 

rule myrule {

 

when CLIENT_ACCEPTED {

 

if { [persist lookup source_addr [IP::client_addr]] eq "" } {

 

set hsl [HSL::open -proto UDP -pool syslog_server_pool]

 

HSL::send $hsl "[IP::client_addr]:[TCP::client_port]"

 

}

 

}

 

}

 

 

Question:

 

 

1> Is it mandatory to call the variable name as 'hsl' ?

 

2> What would the LTM store in this variable 'hsl', if the i-rule is executed simultaneously by 2 different virtual servers at the same time ?
