To handle different methods differently: Many of my HTTP handlers contain nothing but a switch statement like this:

switch r.Method {
   case "GET":
       // Serve the resource.
   case "POST":
       // Create a new record.
   case "PUT":
       // Update an existing record.
   case "DELETE":
       // Remove the record.
   default:
       // Give an error message.
}
