An LTM Specialist configures the following iRule on an LTM device:

when HTTP_REQUEST {
if {[string tolower [HTTP::uri]] contains "/URI1/" } {
 pool Pool1
}
elseif {[string tolower [HTTP::uri]] contains "/URI2/" } {
 pool Pool2
}
elseif {[string tolower [HTTP::uri]] contains "/URI3/" } {
 pool Pool3
}
else { pool Pool4}
}
Given the following request: http://www.example.comURI1/index.html?fu=bar&pass=1234

Which pool will be selected by the iRule?
