You’ve likely seen a ‘404’ or then again assuming a server is battling, maybe a ‘500’ however you won’t ever see a 301 or several different codes recorded beneath.
Typically, when HTTP Status Codes are alluded to, individuals are discussing the HTTP status code joined with the HTTP reason express.
For instance, one of the most notable status codes is 404: Not Found.
For instance, a 301 redirect will convey the information to the people visiting the sites or even bots that the page has moved permanently somewhere else.
As a guest to a site, more often you wouldn’t see these codes except if something turns out badly, (for example, the previously mentioned 404 status code), yet servers in all actuality do likewise send status codes when exchanges are done effectively – you simply don’t see them.
How many HTTP status codes are there?
The primary digit of every three-digit status code starts with one of five numbers, 1 through 5; you might see this communicated as 1xx or 5xx to show status codes there.
Common HTTP status code classes:
Every one of these codes includes an alternate class of server reaction.
1xx Status Code – Informational responses:
This is shown when the server is taking time to think through the request you have just sent in.
2xx Status Code – Success!
This means that all is good and the server has successfully processed the request sent in by the browser by giving the expected or the desired response.

Most Common HTTP Status Codes
This is one of the silent Status Codes/Server Response Codes. This implies that the request was received by the server and was handled effectively.
301: Moved Permanently
The asset that was mentioned has been moved to another permanent and new URI, and the server is processing and redirecting your request to the new URI.
Note: An URI is a Uniform Resource Identifier, which is a series of characters used to recognize an asset, and can be a finder, a name, or both.
A subset of these that is all the more usually known about are URLs – Uniform Resource Locators.
In the comparable outlook that all canines are creatures, however not all creatures are canines, all URLs are URIs, yet not all URIs are URLs!
The asset that was mentioned has been moved to another temporary and new URI, and the server is processing and redirecting your request to the new URI.
However, for future requests, it will attempt to utilize the first area once more.
For the request to be effectively handled, client validation is required.
Assuming you are seeing the 401-status code, this implies the header in your request did not contain the authorization codes that were important to view the page contents.
This means that the server has received the request from the browser and understood what should be shown or given as a result.
Still, the server will not process the request or refuse to process the request at the time.
Indeed, even with authorization, the request would not find success.
404: Not Found
The server could not track down anything that matched the mentioned URI, and it is difficult to let us know whether this is transitory or permanent.
This is frequently utilized either when a server would rather not uncover explicitly why a request was denied, or then again if no other reaction is applicable at the moment.
500: Internal Server Error
An error has happened in the actual server which kept it from finishing the request.
This is a conventional, default message that is utilized when no different codes are applicable in the case or at the moment.
503: Service Unavailable
The server could not deal with your HTTP demand at that point. This could be because of a server crash, server over-burden, server maintenance, or other different reasons.
It is almost always temporary and is a code that is typically set up until the issue has been fixed or resolved.
