Combining various iRules

Maybe this?

when HTTP_REQUEST {
   switch [string tolower [HTTP::path]] {
      "/info.aspx" {
         HTTP::redirect "http://subdomain.oursite.com/default.aspx?[http::query]"
      }
      "/login/default-login.aspx" {
         HTTP::redirect "https://oursite.com[HTTP::uri]"
      }
      "/forms/buy.aspx" {
         HTTP::redirect "https://oursite.com[HTTP::uri]"
      }
   }
}

I think it's better to try to combine all of the iRules which could send a redirect into one as this forces you to consider each piece of logic together. Disabling the HTTP_REQUEST event can be problematic if the client could make multiple HTTP requests over the same TCP connection. If they do, and you disable the HTTP_REQUEST event, no other HTTP requests are processed in the iRule for the duration of the client's TCP connect to the VIP.
