Using an iRule to add source address affinity persistence.

Question

Hello, i'm trying to figure out if there is a way to add a persistence profile (60 minute source address affinity) only to the pool members in the below irule. Basically we're doing hostname mapping via irule and only need a 60 minute persistence profile on the 3xxx pools. Any help would me much appreciated. Thanks!&nbsp;when HTTP_REQUEST {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if {[string tolower [HTTP::host]] equals "example.100.f5.com"} {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;node 10.10.10.77:44351&nbsp;&nbsp;&nbsp;&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;elseif {[string tolower [HTTP::host]] equals "example.200.f5.com"} {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;node 10.10.10.77:44358&nbsp;&nbsp;&nbsp;&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;elseif {[string tolower [HTTP::host]] equals "example.300.f5.com"} {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;node 10.10.10.77:44359&nbsp;&nbsp;&nbsp;&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;elseif {[string tolower [HTTP::host]] equals "example.400.f5.com"} {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pool Treas_CRM-UAT_3259_Pool &lt;-- need 60 minute source address affinity profile&nbsp;&nbsp;&nbsp;&nbsp;}	&nbsp;&nbsp;elseif {[string tolower [HTTP::host]] equals "example.500.f5.com"} {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pool Treas_ECC-UAT_3251_Pool &lt;-- need 60 minute source address affinity profile&nbsp;&nbsp;&nbsp;&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;elseif {[string tolower [HTTP::host]] equals "example.600.f5.com"} {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pool Treas_BW-UAT_3258_Pool &lt;-- need 60 minute source address affinity profile&nbsp;&nbsp;&nbsp;&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;else { discard }}&nbsp;
