HTTP 405 Method Not Allowed

🛠️ What is HTTP 405 Method Not Allowed?

The HTTP 405 Method Not Allowed status code indicates that the request method is not supported by the target resource. It occurs when the server recognizes the request method, but the method is disabled and cannot be used on the requested resource.

⭐ Why is HTTP 405 Important in Technical SEO?

HTTP 405 errors can impact user experience and SEO. When a method is not allowed, it may lead to visitors encountering broken functionalities or not being able to access certain resources, potentially increasing bounce rates and affecting overall site performance.

⚙️ How Does HTTP 405 Work?

1. A client sends an HTTP request with a specific method (e.g., POST, GET).
2. The server checks if the method is allowed and applicable for the resource.
3. If the method is not allowed, the server responds with a 405 status code.
4. The client is informed that the method is not permitted for the requested resource.

📌 Examples of HTTP 405 Errors

• Attempting to use a GET request to submit a form that requires POST.
• A DELETE request is sent to a server that supports only GET and POST methods.
• Trying to execute a PUT request to update resources on a server that only allows POST requests.

✅ Best Practices to Avoid HTTP 405 Errors

• Ensure that the server supports all necessary HTTP methods for each resource.
• Check and configure server-side ACLs to allow appropriate request methods.
• Map out all endpoint functionalities to determine the correct HTTP methods required.
• Monitor logs to quickly identify requests that result in 405 and rectify them.

⚠️ Common Mistakes That Cause HTTP 405

• Misconfiguring server or application settings, disallowing valid request methods.
• Not updating server method support when additional functionality is added.
• Overlooking API documentation leading to incorrect usage of request methods.

• cURL – to test and debug different request methods in a terminal.
• Log Management Tools – like Splunk, to identify 405 errors in server logs.
