#Ubuntu simple ftp server code#
The class of a status code can be quickly identified by its first digit: HTTP status codes are three-digit codes, which are grouped into five different classes. When accessing a web server, every HTTP request received is responded to with content and a HTTP status code. Protocols such as Hyper Text Transfer Protocol over Secure Sockets Layer (HTTPS), and File Transfer Protocol (FTP), a protocol for uploading and downloading files, are also supported. The most common protocol used to transfer web pages is the Hyper Text Transfer Protocol (HTTP). For example, to view the home page of the Ubuntu Web site a user will enter only the FQDN: To view the community sub-page, a user will enter the FQDN followed by a path: Transfer protocols Users enter a Uniform Resource Locator (URL) to point to a web server by means of its Fully Qualified Domain Name (FQDN) and a path to the required resource. The response is usually a web page in the form of HTML documents – which may include images, style sheets, scripts, and text. The clients communicate with the server by sending HTTP requests.Ĭlients, mostly via web browsers, request specific resources and the server responds with the content of that resource (or an error message). The primary function of a web server is to store, process and deliver web pages to clients. Multi-node configuration with Docker-Composeĭistributed Replicated Block Device (DRBD)
