What are HTTP Error Codes
While browsing the internet you may have come across error messages like "404 not found" or "403 not permitted". But what are these messages and where do they come from?
These error messages are being sent to your browser from the web server that you are trying to access.
What do the Numbers mean?
The most common error messages are 404, 500 and 503.
- 404 - File not Found. Either a link you have clicked or the address you typed in was incorrect. The Domain Name is correct but the requested file is not.
- 500 - Internal Server Error. This is a generic error message that indicates something is wrong but it just isn't sure exactly what it is
- 503 - Service Unavailable. The server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.
