iRule works but getting browser error, help!

At first glance, it looks good to me (besides the double slash in the "www.test1" and www.test2 redirects - unless this is what you intended). What kind of errors are you getting?

Here's an example of using a switch statement for your reference (with test1* and www.test1* redirecting to the same uri).

when HTTP_REQUEST {
  if { [HTTP::uri] starts_with "/TrafficUI" } {
    pool Testy
  } else {
    switch -glob { [HTTP::host] } {
      "test1*" -
      "www.test1*" {
        HTTP::redirect "http://www.test1.com/TrafficUI/mscui/page.aspx?cid=1&ptid=5"
      }
      "test2*" -
      "www.test2*" {
        HTTP::redirect "http://www.test2.com/TrafficUI/mscui/page.aspx?cid=1&ptid=10"
      }
      "test*" {
        HTTP::redirect "http://www.google.com/"
      }
    }
  }
}
