Server does not check the HTTP method of the request

If the rest of the request looks like a gRPC request, the server will accept incorrect HTTP methods, such as “DELETE” or “PUT”. If the server generates an error status, it would be because some other issue was encountered in processing the request.

Ideally, the server would check some basics of the request before even attempting to process it as a gRPC request, the HTTP method and the content-type are the main attributes it should check to classify the request as gRPC or not.
