Persist only specific IPs destined for a VS

It should be more efficient to do a qualifying compare and an action if it meets your criteria.

 

 

If client IP Address is in the matchclass data set, do this....

 

 

Your code is doing a variable set and then a compare.

 

 

Set hostip variable if the clients IP Address is in the matchclass data set.

 

Then

 

If the hostip is not equal to nothing / null, do this....

 

 

iRule efficiency is generally sacrificed for readability, but if this iRule has to be processed a couple of hundred times per second, it could add up to some processing latency.

 

 

I would try this. It does the compare and either applies the persistence or releases the traffic to the pool of the Virtual Server it is applied to:

 

when CLIENT_ACCEPTED {
    if { ([matchclass [IP::remote_addr] equals $::TestDataGroup ]) } {
        persist source_addr 28800
    }
}
