"Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989."
Understanding the basics of HTTP including methods, status codes, and headers is necessary to work with Rickshaw which is an HTTP server framework written in Node.js.
HTTP Protocol: This topic covers HTTP as a communication protocol used by computers to request and deliver data over the web.
HTTP Requests and Responses: This pertains to the process of sending and receiving data between the client and server, which involves different methods and status codes.
URLs: Uniform Resource Locators or URLs provide a means to locate resources on the web, such as web pages, images, and videos.
HTTP Headers: This topic relates to the information transmitted within an HTTP request or response that helps in identifying and describing the requested resource.
Queries and Parameters: This involves the use of queries and parameters in URLs to retrieve specific information in the HTTP request.
Forms: This covers the forms used to collect data from users and the ways to submit data to the server through HTTP requests.
Cookies: This topic pertains to the use of cookies to store and track user information between HTTP requests.
Session Management: This involves the use of sessions to enable continuity of user experience between HTTP requests.
Authentication and Authorization: This pertains to the methods of authenticating users and granting access to resources based on the user's identity.
Caching: This topic covers the caching mechanism employed by browsers, proxies, and servers to reduce response time and network bandwidth consumption.
Security: This involves the security practices and protocols used for secure communication over HTTP, such as HTTPS and SSL.
RESTful Web Services: This pertains to the web services that follow the principles of Representational State Transfer (REST), which involves the use of HTTP methods, URLs, and data formats to perform CRUD operations on resources.
APIs: This topic covers the use of APIs to enable applications to interact with web services and exchange data over HTTP.
Load Balancing: This involves the use of load balancers to distribute HTTP requests across multiple servers to improve performance, reliability, and availability.
Compression: This topic covers the use of different compression techniques, such as gzip and deflate, to compress HTTP responses and reduce network latency.
Request methods: These are the actions that a client can request the server to perform. Examples include GET, POST, DELETE, PUT, etc.
Status codes: These are three-digit numbers that are returned by the server to indicate the outcome of a request. Examples include 200 OK, 404 Not Found, 500 Internal Server Error, etc.
Headers: These are metadata sent along with the HTTP request or response that includes information about the message body or the connection being used.
Cookies: These are small text files that are sent from the server to the client and stored by the client, allowing the server to recognize the client's identity across different requests.
URL encoding: This is the process of encoding special characters in a URL so that they can be safely transmitted over the internet.
Query parameters: These are key-value pairs that are appended to the end of a URL to specify additional information about the request.
Caching: This is the process of storing copies of frequently accessed resources in order to reduce the time it takes to load them.
Authentication and Authorization: These are mechanisms used to ensure that only authorized users can access certain resources on a server.
HTTPS: This is a secure version of HTTP that uses encryption to protect sensitive information transmitted between the client and server.
"The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems."
"Hypertext documents include hyperlinks to other resources that the user can easily access."
"The first HTTP version, named 0.9."
"The Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C)."
"HTTP/1 was finalized and fully documented (as version 1.0) in 1996."
"It evolved (as version 1.1) in 1997 and then its specifications were updated in 1999, 2014, and 2022."
"Its secure variant named HTTPS is used by more than 80% of websites."
"HTTP/2, published in 2015, provides a more efficient expression of HTTP's semantics 'on the wire'."
"As of April 2023, it is used by 39% of websites."
"HTTP/3, the successor to HTTP/2, was published in 2022."
"HTTP/3 uses QUIC instead of TCP for the underlying transport protocol."
"HTTP/3 is now used on over 26% of websites."
"HTTP/3 is supported by most web browsers, i.e. (at least partially) supported by 94% of web browsers."
"Like HTTP/2, it does not obsolesce previous major versions of the protocol."
"Support for HTTP/3 was added to Cloudflare and Google Chrome first."
"HTTP/3 has lower latency for real-world web pages, if enabled on the server, load faster than with HTTP/2, and even faster than HTTP/1.1, in some cases over 3× faster than HTTP/1.1."
"HTTP/1.1 is still commonly enabled."
"HTTP/1.1 is used by over 97% of users."
"HTTP is the foundation of data communication for the World Wide Web."
