    Hi,

    Here is an irule example that do the same as your own irule : 

    when HTTP_REQUEST {
    if { [active_members pool1] <1 or [active_members pool2] <1 or [active_members pool3] <1} {
        if { [URI::basename [HTTP::uri]] eq "logo.jpg" } {
            HTTP::respond 200 content [ifile get logo.gif] "Content-Type" "image/gif"
        } else {
            HTTP::respond 200 content [ifile get error.html] "Content-Type" "text/html"
        }
    } else {
        switch -glob [HTTP::uri] {
            "/foo1*"  { pool pool1 }
            "/foo2*" { pool pool2 }
            "/foo3*" { pool pool3 }     
        }       
    }           
}

    Thanks very much. I made a mistake in my example as well but this looks a lot cleaner.
