4XX HTTP Status Codes
If you are new to the internet and have just started browsing online content, you will likely encounter various types of HTTP errors, with 4XX error types being quite common. These messages are displayed when there’s a problem communicating between a web server and a browser. These 4XX errors can be confusing and intimidating for any individual. Therefore, it is natural to wonder whether something has gone wrong on your side or if there is a problem with your system.
What is a 4XX Error? The 4XX error code means that there’s a problem with the client’s request i.e. the error is caused by the user or the client device rather than the server. The client-side error response range is from 400 to 499. These errors are different from 5xx errors, which indicate a server-side error. These errors can occur due to a variety of reasons and can have a negative impact on SEO as well as user experience
What are the common causes of 4XX errors? ● Incorrect URLs or links: This happens when a user tries to access a page with a wrong URL or a broken link. ● Expired or invalid sessions or cookies: When a user tries to access a website with an expired or invalid session, they’ll encounter a 4xx error. ● User authentication issues: When a user tries to access a page without the proper authentication or credentials, they’ll receive a 4xx error. ● Server or website configuration errors: These errors happen when there’s an issue with the server or website configuration, such as the web server is down, the server is overloaded, or there’s a misconfiguration.
How 4xx errors are different from 5xx errors? 4xx errors and 5xx errors are HTTP status codes that indicate different types of errors that can occur when a user tries to access a web page. The main difference between these two categories of errors is their origin or source. 4xx errors are client-side errors, which means that the problem originates from the user’s side, such as a mistyped URL or an outdated cached version of the page. Some common examples of 4xx errors include “404 Not Found” and “403 Forbidden”.
