Troubleshoot a Classic Load Balancer: HTTP errors - Elastic Load Balancing
The HTTP method (also called the verb) specifies the action to be performed on the resource receiving an HTTP request. The standard methods for HTTP requests are defined in RFC 2616, Method Definitions. The standard methods include GET, POST, PUT, HEAD, and OPTIONS. Some web applications require (and sometimes introduce) methods that are extensions of HTTP/1.1 methods. Common examples of HTTP exte

Configure connection draining for your Classic Load Balancer - Elastic Load Balancing
To ensure that a Classic Load Balancer stops sending requests to instances that are de-registering or unhealthy, while keeping the existing connections open, use connection draining. This enables the load balancer to complete in-flight requests made to instances that are de-registering or unhealthy. When you enable connection draining, you can specify a maximum time for the load balancer to keep c
