Pool selection based on URI

the irule never match URI : /app2/login

and to redirect /app1 to /app1/ do a redirect and not HTTP::uri replacement. (I commented this part)

when HTTP_REQUEST {
    switch [string tolower [HTTP::uri]] {
        "/app1" {
            pool p_app1
            HTTP::uri "/app1/"
        }
        "/app1*" {
            pool p_app1
        }
        "/app2" {
            HTTP::redirect "/app2/"
            pool p_app2
            HTTP::uri "/app2/"
        }
        "/app2*" {
            pool p_app2
        }
    }
}
