iRule node directive not working with SSL terminated virtual server

I'm having trouble with an iRule running on a virtual server handling https traffic - specifically with the "node" directive. The situation: I have a pair of virtual servers, I'll call them Port80...

    Have you considered changing the switch to something like this? Seems buggy that http works but not https, but I would think the query is the better aspect to select from.

    switch -glob [string tolower [HTTP::query]] {
  "s=prodapp2" { node 192.168.196.43 }
}

Maybe ekaleido's answer was the key. I changed the "switch -glob [string tolower [HTTP::uri]]" to "switch -glob [string tolower [HTTP::query]]" and it started working. Note - I had already added port 80 to the "node" command. The full snippet now looks like:

if {[string tolower [HTTP::uri]] contains "_monitor" } {
 switch -glob [string tolower [HTTP::query]] {
    "*prodapp2*" {
       node 192.168.196.23 80 }
    "*prodapp3*" {
       node 192.168.196.33 80 }
    "*prodapp4*" {
       node 192.168.196.43 80 }
 }
}

And all is well. I don't understand why it sometimes finds a string located in the query string within HTTP::uri and other times not but that's okay...

Thanks!
