Combining iRules -> switch statements

I have a master iRule which is doing simple redirecting based on http::uri I would like to add an additional set of rules that tries to do a string match for a specific URI typed in, such as: ...
application delivery
dev
devops
iRules

Hi Joe,

You can nest switch cases as shown below. I've split out the host and URI check you were trying to do together into separate switch cases. Also, you don't need an explicit return statement in each switch case. Once a switch case matches, no other switch cases in the same statement will be evaluated. 


when HTTP_REQUEST {
    Check the Host header value, set to lowercase
   switch -glob [string tolower [HTTP::host]] {
      "events.oursite.com" {
          Check the URI, set to lowercase
         switch [string tolower [HTTP::uri]] {
            "/event.aspx?event=someevent2010" {
               HTTP::redirect "https://sub.domain.com/events/some-url-2010/home.aspx"
            }
         }
      }
      "*somedomain1.*" {
         HTTP::redirect "https://somesite.com/EventOverview.aspx?Event=someevent1"
      }
      "*somedomain2.*" {
         HTTP::redirect "https://anothersite.com/EventOverview.aspx?Event=someevent2"
      }
      "*somedomain3.*" {
         HTTP::redirect "https://oursite.com"
      }
   }
}
