Catch a specific URL and redirect it

I have an existing iRule which uses a switch statement to catch a request no matter the case (string tolower) and redirect.

For some reason, the iRule is not catching and redirecting - I simply want to do this:

http://oursite.com/EventOverview.aspx?Event=some2010

Should redirect to:

http://ourothersite.com/events/event-name.aspx

Can anyone tell me why this below wouldn't work? 

  
  when HTTP_REQUEST {   
     switch -glob [string tolower [HTTP::uri]] {    
       "/EventOverview.aspx?Event=some2010" {   
        HTTP::redirect "http://ourothersite.com/events/event-name.aspx"   
      }   
    }   
  }

    You are converting the URI to lower case and then comparing it to a mixed case string and that will always fail. Lower case your match string and all should be good. 

    when HTTP_REQUEST { 
   switch -glob [string tolower [HTTP::uri]] { 
     "/eventoverview.aspx?event=some2010" { 
       HTTP::redirect "http://ourothersite.com/events/event-name.aspx" 
     } 
   } 
 }

    Yikes I should have caught that - cloudy thinking yesterday.

     

     

    Thanks again for your help!

    How can I add an or, so that I can look for 1 of 2 URIs and redirect to one? http://oursite/1 or http://oursite/2 to http://oursite/3. I'm trying to keep this simple as I have many pairs to do this with on the same VS.

     

     

    /1 or /2 to /3.

     

    /4 or /5 to /6.

     

    /7 or /8 to /9, and so on.

     

     

    Thanks
