What is a Web Error?

A web error is an issue encountered when attempting to reach a webpage or interact with content on the internet. These errors can originate from various sources, such as the client's browser, the server hosting the website, or network issues in between. There are a few different types:

  • Client-Side Errors (4xx): The request contains bad syntax or cannot be fulfilled. 404 Not Found is the most recognized error, indicating that the requested page doesn’t exist on the server. Meanwhile, a 403 Forbidden error means that access to the requested resource is denied.
  • Server-Side Errors (5xx): Problems that prevent the server from fulfilling a request. The 500 Internal Server Error is a generic error message when the server encounters an unexpected condition. A 503 Service Unavailable error suggests the server is temporarily unable to handle the request.

We’ll get more specific about the most common errors below. But just know this - understanding web errors is crucial for website operators because these issues can negatively impact the user experience, potentially leading to a loss of traffic and revenue.
Effective diagnosis and prompt resolution maintain a website's integrity and reliability. Identifying the types of errors that occur, such as those listed on HTTP response status codes, allows for targeted troubleshooting and informs corrective measures.

What are the Most Common Web Errors?

In navigating the web, users and developers commonly encounter a variety of errors. These errors, signifying different issues, can range from server malfunctions to authorization problems. Understanding each error type is essential for both troubleshooting and ensuring a seamless user experience.

500 Internal Server Error

The server encountered an unexpected condition that prevented it from fulfilling the request. This generic catch-all error often requires server-side debugging by the website's technical team.

401 Unauthorised

This error indicates that the requested resource is restricted and requires authentication. If a user is not logged in with the correct credentials, they cannot access the resource.

400 Bad Request

A 400 Bad Request error signifies that the server cannot process the request due to a client error, such as incorrect syntax or size too large.

403 Forbidden

Even with proper authentication, users may encounter a 403 Forbidden error if they try to access a resource for which they do not have proper permissions.

404 Not Found

This is one of the most common website errors indicating that the server could not find the requested URL. The page might have been removed or the user may have followed a broken link.

501 Not Implemented

The server does not support the functionality to fulfill the request, typically due to the method being unrecognized or lacking capability.

502 Service Temporarily Overloaded

A 502 error signifies that the server, while acting as a gateway or proxy, received an invalid response from the upstream server.

503 Service Unavailable

The 503 Service Unavailable error means the server is currently unable to handle the request due to temporary overloading or maintenance.

Connection Refused by Host

Users see this error when the server is refusing to connect, often due to server overload or maintenance being performed on the web server.

File Contains No Data

When encountering a File Contains No Data error, it means the server issued a response, but the file that the server sent contains no information.

Cannot Add Form Submission Result to Bookmark List

This error appears when a user attempts to bookmark the result of a form submission, which is not a static page and therefore cannot be bookmarked.

Helper Application Not Found

A Helper Application Not Found error occurs when the browser cannot find the appropriate software to handle a particular file type or protocol.

TCP Error Encountered While Sending Request to Server

A TCP error indicates problems with the transmission control protocol, which may involve packet loss or a faulty connection when sending a request.

Failed DNS Look-Up

This error implies that the domain name system (DNS) lookup failed, meaning the server associated with the domain name could not be found.

408 Request Time-Out

A server returns the 408 Request Time-Out error when it closes an idle connection because the client took too long to send a request.

Prevention of Web Errors Going Forward

To prevent errors in the future, developers should prioritize a robust approach to error handling. Emphasizing the importance of clear and concise error messages helps in diagnosing and rectifying issues efficiently.
Adopting best practices in web development is critical; this includes rigorous testing of applications under various conditions and planning for error management throughout the application's lifecycle. The following strategies are essential:

  • Routine Code Review: Regularly reviewing code can catch potential errors early. Pair programming or having another developer review code can provide an outside perspective that may identify issues that the original coder missed.

Implementing Error Tracking Tools: Tools that monitor applications in real-time can alert developers to errors as they occur, allowing for immediate action.

  • User Input Validation: Ensuring that all user inputs are validated can reduce errors. Applications should check, sanitize, and handle user data appropriately before processing.
  • Server-Side Logging: Keep detailed logs of server-side errors.
  • Client-Side Logging: Use scripts to report client-side issues.
  • Preventive Coding Techniques: Use try-catch blocks for sections of code that might throw an error. Include finally clauses where needed to clean up resources.

To further enhance stability and performance, developers should consider optimizing web script stability. This not only ensures a better user experience but minimizes interruptions caused by script errors.
Leveraging content delivery networks (CDNs) to reduce load times, implementing responsive design for various devices, and keeping software dependencies up to date are also key elements in reducing errors.
