HTTP:URI no ending slash

If I understand your request, something like this should work (very similar to what you already have).

when HTTP_REQUEST {
     if { [string tolower [HTTP::uri]] starts_with "/test" } {
          pool A
     } else {
          pool B
     }
}

Now, if you mean that you want to differentiate between "/test" (explicit) or "/test*" (something that starts with "/test"), then your conditional should flow from most specific to least specific. For example, if URI equals "/test", do A, else if URI starts with "/test", do B.
