If you encounter an unfamiliar HTTP error, don’t worry! We want to help you navigate through this content in a very friendly and easy manner to understand what types of errors can occur and how to deal with them.
Always when our programs do not run correctly, and sometimes we may face an HTTP error that we cannot identify the cause. These errors, which we refer to as HTTP errors, are not always clear about what happens with our request on the server.
When we want to open a website, we may send requests to the server and in response, we might receive codes like 200, 404, 500, etc. Each code has its own story. For example, a code 200 means: "Everything is okay!" but a code 404 tells us that the page we are looking for could not be found.
Let’s take a look at a list of some of these codes and get more familiar with them. In the same order, a code 500 indicates the server encountered an error that couldn’t complete the request. By recognizing these errors, we can more easily track issues with our programs.
Review of Common HTTP Errors
One of the most common errors is error 404, which means the requested page could not be found. There can be multiple reasons for this error, from deletion or renaming of the file to user error when typing the address.
HTTP/1.1 404 Not Found
Content-Type: text/html
<html>
<head><title>404 Not Found</title></head>
<body>
<h1>Not Found</h1>
<p>The requested URL was not found on this server.</p>
</body>
</html>
Using the above format to send a 404 error in a browser is common. Let’s go line by line to explain it:
HTTP/1.1 404 Not Found
: This line displays the HTTP status and indicates the page was not found.Content-Type: text/html
: This refers to the type of content (Content-Type) defined as HTML.- Tags
<html>
and other tags structure a simple HTML page that displays the error content. <h1>
is for displaying the main title (in this case, "Not Found").<p>
: Information regarding the error, here it states that the URL could not be found.
