http options to list endpoints

 To get all the endpoints in a REST application, you can use the HTTP OPTIONS method to make a request to the server. The server should respond with a list of all the endpoints that are available on the application, along with the HTTP methods that are supported for each endpoint.

Here is an example of how you might make a request to the server to get all the endpoints:

OPTIONS / HTTP/1.1
Host: www.example.com

The server should respond with a Allow header that contains a comma-separated list of the HTTP methods that are supported by the server. This can be used to get a list of all the endpoints that are available on the application.

Here is an example of how the server might respond to the request:

HTTP/1.1 200 OK
Allow: GET, POST, PUT, DELETE, HEAD, OPTIONS

In this example, the server supports the GET, POST, PUT, DELETE, HEAD, and OPTIONS methods for all endpoints on the application.
