What is Server Response Code?
Server Response Code represents the status of the communication between a client and a web server. Whenever you enter a website URL in your browser's address bar, it sends requests to the server which responds with an HTTP status code. These codes indicate whether your request was successful or not.
The Server Response Code usually consists of three-digit numbers ranging from 100 to 500. The first digit defines the general category of response, while the last two digits do not have any classifying role but serve as error identifiers. For example,
404 Not Found, and
500 Internal Server Error.
If all goes well, you will most likely receive a 200-class response code that indicates success such as "200 OK" This shows that your requested resource has been successfully delivered by the server to your device for displaying on your screen.
The Different Types of Server Response Codes:
The Informational Codes - Fall under range 100-199, these codes represent useful information about ongoing processes and meanwhile do not belong strictly to either an error nor success group.
The Success Codes - Represented by series ranging from (200-299), These codes show that your request was understood correctly by the server, which means data or content is being sent back as required including “200 OK” and “201 Created”.
The Client Error Codes - Fall under range (400-499), these codes are generated by a client-side problem where an invalid URL or any other incorrect details have been entered into their web browser's input field. Common examples include '404 File Not Found,' '403 Forbidden Access,' and '401 Unauthorized.'
Breaking Down the Server Response Codes:
The Redirections - These codes (300-399) suggest to a client that it should take additional actions to complete the request. The server responds with this when trying to redirect your web browser from one URL address to another, which are no longer valid or have been moved.
The Server Error Codes - Represented by series ranging from (500-599). These status codes represent internal server errors, indicating that something went wrong on the Webserver's end before they could fulfill your requests. Examples include “500 Internal Server Error” and “503 Service Unavailable”. When you encounter these types of issues, it is likely that the webmaster needs to rectify them first before you can gain access again.
The Client Help Error Codes - Situated under range 400-499 - If you're encountering error codes in this category ('400 Bad Request', for example), there's a good chance that resolution will depend on how well-informed either the actual server is or its support staff at your hosting provider.
