You should be able to do this as part of a policy as it is computationally more efficient. However you could use an irule such as this to select your pools based on a cookie value:

when HTTP_REQUEST {
    if {[HTTP::cookie exists "APP_S"]} {
        if {[HTTP::cookie value "APP_S" eq "Type_1"]} {
            pool Pool_Type_1
        } elseif {[HTTP::cookie value "APP_S" eq "Type_2"]} {
            pool Pool_Type_2 
        } else {
            pool Pool_default
        }
    }
}
