👉 The HTTP (Hypertext Transfer Protocol) fluid is a data format used to carry the actual content of an HTTP request or response, similar to how HTML carries web page structure but for data transfer. It is essentially a binary representation of the data exchanged between a client (like a web browser) and a server. The HTTP fluid can include various types of media, such as text, images, audio, and video, along with headers that provide metadata about the content, like content type, encoding, and security measures. This format is crucial for web communication as it ensures that the data is properly formatted, transmitted securely (often using HTTPS), and interpreted correctly by the receiving system.
