the Hypertext Transfer Protocol (HTTP), an important part of that structure is a status code. Introducing HTTP Status Codes Status codes are three-digit netbackup common error codes numbers.

200, that represents a successful response to the request. There are status codes that start with 1. These represent informational messages. These are rarely seen. A code of the form 3xx represents a redirection response. Typically, the browser will handle these without user interaction and get the resource from the new location instead. Error codes come in the form of 4xx and 5xx statuses. Error codes at the 400 level mean there was a common computer error codes client-side error — think of something like the user typing the wrong URL in the address bar. Error codes at the 500 level mean there was a server-side error — think of something like the database server going down or perhaps running out of disk space. Five of the most popular error codes are 403, 404, 500, 503, and 504. Let’s look at each of these in a little more detail. 404 Not Found The most common error code you run into is a 404 error. The 404 status code means the requested resource is no longer available or, more specifically, just not found. Was it ever available there? You don’t know. You do know it isn’t available there now. What are some of the reasons for a 404 error? Typos are a common reason for getting a 404 error. A missing or extra letter in a typed-in url, or a wrong domain name can often result in a 404 error. Another reason for 404 errors isn’t typos; it is the aging of the web. When someone writes an article or blog, that person might link to a secondary source to provide additional information for the article. Now imagine revisiting said article six months or six years later. If what was linked to is no longer on the web, a 404 err

HTTP status codes are three-digit codes, and are grouped into five different classes.

There are many situations that could cause a web server to respond to a request with a particular error code--we will cover common potential causes and solutions. Client and Server Error Overview Client errors, or HTTP status codes from 400 to 499, are the result of HTTP requests sent by a user client (i.e. a web browser or other HTTP client). Even though these types of errors are client-related, it is often useful to know which error code a user is encountering to determine if the potential issue can be fixed by server configuration. Server errors, or HTTP status codes from 500 to 599, are returned by a web server when it is aware that an error has occurred or is otherwise not able to process the request.

> ref > http status codes HTTP Status Codes Every HTTP transaction has a status code sent back by the server to define how the server handled the transaction. Here is a list of the most common ones. List of Common HTTP Status Codes 200 OK 300 Multiple Choices 301 Moved Permanently 302 Found 304 Not Modified 307 Temporary Redirect 400 Bad Request 401 Unauthorized 403 Forbidden 404 Not Found 410 Gone 500 Internal Server Error 501 Not Implemented 503 Service Unavailable 550 Permission denied HTTP Status Code - 200 OK The request has succeeded. The information returned with the response is dependent on the method used in the request. Back to top HTTP Status Code - 300 Multiple Choices The requested resource has different choices and cannot be resolved into one. For example, there may be several index.html pages depending on which language is wanted (such as Dutch). Back to top HTTP Status Code - 301 Moved Permanently The requested resource has been assigned a new permanent URI and any future references to this resource should use one of the returned URIs. Back to top HTTP Status Code - 302 Found The requested resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. Back to top HTTP Status Code - 304 Not Modified If the client has performed a conditional GET request and access is allowed, but the document has not been modified, the server SHOULD respond with this status code. The 304 response MUST NOT contain a message-body, and thus is always terminated by the first empty line after the header fields. If the client has done a conditional GET and access is allowed, but the document has not been modified since the date and time specified in If-Modified-Since field, the server responds with a 304 s
