Error 405 Method Not Allowed: Explanation and solutions

HTTP Error “405 Method Not Allowed”: How to solve the problem

HTTP is indispensable as a mediator between the browser and web server: Both communicate with each other using the transmission protocol on the application layer by sending various types of messages.

But what...
