From time to time, you will come across server error messages when trying to access a web page or website. They can be quite annoying especially if you can’t differentiate one error message from the other. The 4xx Client Error group of HTTP status codes includes errors where the request for a web page contains bad syntax or is incapable of filling, presumably by the fault of the client. These errors can be avoided, or overcome by using a few simple techniques. Here are some of the common Client Error messages that you might come across when surfing the Web, and what they mean.

400 - Bad File Request

The 400 error indicates that the server can’t figure out the URL you requested. It could be because the syntax in the URL is incorrect. Check for wrong punctuation marks, incorrect upper case or lower case letters, colons, and slashes.

401 - Unauthorized

The 401 error usually occurs when the server is not receiving the correct encryption key (ID or password) necessary for entry, from the client. Try again, typing the password correctly, as passwords are often case-sensitive.

403 - Forbidden/Access Denied (more…)
