Which Kind of HTTP Response Is It?

About this interactive

From the lesson: - **2xx, success:** 200 OK, the page is delivered; others in the range (201, 202...) are other kinds of success. - **3xx, redirection:** the resource is somewhere else, and the browser is sent there: another page, another site, or HTTP on port 80 sent on to HTTPS on 443 (301, 302). - **4xx, client error:** the request itself is the problem, such as 404 Not Found for a page or a favicon that does not exist. - **5xx, server error:** the server understood the request but could not complete it, for example because it cannot reach its database. - **1xx** codes are informational.

Key terms

Hypertext Transfer Protocol: An application-layer protocol that defines how web browsers and servers communicate to request and deliver web pages and other content, operating over TCP on port 80. HTTP transmits data in plaintext, which is why it has been largely replaced by HTTPS for sensitive content.
Hypertext Transfer Protocol Secure: The encrypted version of HTTP that wraps web traffic in a TLS session, operating on TCP port 443, so that the data exchanged between a browser and a web server is confidential and cannot be read or modified by an eavesdropper. HTTPS is now the standard for all web traffic, indicated by the padlock icon in a browser.
Uniform Resource Locator: A subset of the URI that specifies the location of a resource by including the protocol, host, path, and resource name.
Uniform Resource Identifier: A string of characters that uniquely identifies a specific resource on the internet, including components such as protocol, host, path, query, and fragment.
