What are HTTP error codes?

HTTP status codes are responses issued for a client’s request made to a server. For example, when you (your web browser) try to connect to your Facebook site (the server).

Based on how the request is handled, the server indicates specific responses. These responses encompass redirects, server errors, customer errors, and others as such. HTTP error codes, now, are not a section of internet pages; instead, they are responses from servers about how the request is handled.
