HTTP/1.0 is a protocol used for transferring data on the World Wide Web. Introduced in 1996, it allows clients, like web browsers, to request resources from servers. Each request is independent, meaning the server does not keep track of previous requests, which can lead to inefficiencies. One key feature of HTTP/1.0 is its simplicity. It uses a straightforward request-response model, where a client sends a request and the server responds with the requested data. However, this version lacks some advanced features found in later versions, such as persistent connections, which allow multiple requests to be sent over a single connection.
