What are Error Codes?

These designated error requirements are how the server informs visitors about an error experienced. There are many different error requirements that a server can provide, but these are a few of the more common requirements.

401 : Unauthorized

Access to the URL source needs user verification which either has not yet been offered, or which has been offered but unsuccessful. This is generally known as security password protection. Unless you have reasonable to do so, it is not suggested to divert a 401 error.

403 : Forbidden

The demand was a legal demand, but the server is declining to reply to it. Compared with a 401 Illegal reaction, authenticating will make no difference. This is usually due to a scripting or data file authorizations issue.

404 : Not Found

This rule indicates that the guest was able to connect with the server, but either the server could not find what was asked for, or it was designed not to meet up with the demand and not expose the purpose. Error 404 should not be puzzled with "server not found" or similar errors, in which a relationship to the location server cannot be made at all.

500 : Inner Server Error

Your web server experienced an surprising situation that avoided it from satisfying the demand by the guest. Generally, something has gone wrong, but the server can not be more specific about the error situation in its reaction to the guest.
