HTTP Status Code 405

The status code 405, also known as "Method Not Allowed", is an error code encountered in communication between web servers and clients (usually web browsers). It indicates that the server understood the request perfectly, but it cannot fulfill it because the specific method used in the request is not allowed for the requested resource.

Here's a breakdown of the scenario:

• You make a request to a web server, for example trying to access a webpage.
• The server acknowledges your request and understands the type of action you're requesting (indicated by the HTTP method in your request). Common HTTP methods include GET (to retrieve data), POST (to submit data), PUT (to update data), and DELETE (to remove data).
• However, the server is configured to disallow the specific method you used for that particular resource. For instance, the server might only allow GET requests for a webpage but you might have mistakenly used a POST request.

In this situation, the server responds with a 405 error code, along with an error message that usually specifies the allowed HTTP methods for that resource. This way, you (or the developer in case of an automated request) can understand the issue and adjust the request accordingly.
