Any way to avoid source persistence based on IP?

Hi guys,

 

Looking for some advice please.

 

I'm looking to implement an alerting function on our estate which aims to hit a hostname.asp url across 4 servers, tally the result then alert if any count is 0 over a period.

 

The problem is that our F5 have simple session persistence so I get a full count for one server and 0 for the rest.

 

Is it at all possible that an iRule could be written to use source persistence EXCEPT to a certain URL? ie, https://myserver.hostname.asp, or even ignore persistence from a static IP?

    Try something like this:

    when HTTP_REQUEST {
if { ([HTTP::host] eq "myserver.hostname.asp") and ([HTTP::uri] eq "/") } {
persist none
}
}
