Nodes requesting their own vip are not triggering the vip's iRule

Colleague of jwhitene here. We have a forwarding VS that auto-maps SNAT when the node requests the DNS name (or IP) that corresponds to its own VS. Source [node IP]/32 Dest [VS IP] Type Standard, All Ports, Source Address Translation Auto Map. It was the only way we could get it to reply to itself. So the request should be going through the iRule. Snippet:

set path [string tolower [HTTP::path]]if { $path starts_with "/foo/" or $path equals "/foo" } { https pool redirect_pool break

But it appears the self-requests are getting directed to the default pool.
