Looking for iRule to forward based on uri

You can use a switch statement for this as well. It's more efficient as you're not performing all three checks if a prior check was true.

when HTTP_REQUEST {

   switch [HTTP::path] {
      "/proposals/AccessControl.htm" {
         HTTP::redirect "http://domain2.com/sub1/Construction/Proposals/AccessControl"  
      }
      "/proposals/Davis.htm" {
          HTTP::redirect "http://domain2.com/sub1/Construction/Proposals/Maintenance"  
      }
      default {
         HTTP::redirect "http://domain2.com/sub1/Construction"  
      }
   }
}

If you have a lot more URIs to check for and they're all exact matches, you could add all of them to a string datagroup with a 'string' of the URI and a value which is the redirect URL. You can check the class wiki page for examples:
