关于[Pushing UI changes from Blazor Server to browser on server raised events]的摘要:
A typical interaction between a web browser and a web server consists of a series of HTTP requests and responses. As opposed to HTTP, a websocket will open a persistent bi-directional connection where multiple messages can be sent back and forth. This also means the server can send messages to the client at any time. Blazor Server is built on SignalR, and SignalR is built on websockets among other techniques. The combination of these technologies allow Blazor Server to push UI changes into the client without the client requesting those changes.
