VerifiedCompared to WebSocket, SSE is lighter to implement, natively supports automatic reconnection, and is the superior engineering choice for unidirectional scenarios where only server-side push is needed.83% similarVerifiedSSE implements one-way server-to-client push over HTTP long connections, and supports reconnection after disconnection via the Last-Event-ID header.82% similarUnverifiedCompared to WebSocket's full-duplex connection, SSE is based on ordinary HTTP response streaming and has stronger penetration through load balancers, CDNs, and firewalls.79% similarUnverifiedSSE 因基于标准 HTTP 协议、天然支持断线重连、无需额外握手开销，成为大语言模型流式输出的主流方案77% similarVerifiedSSE（Server-Sent Events）是一种服务器向客户端单向推送数据的HTTP标准，相比WebSocket更轻量，无需握手协议，天然支持断线重连77% similar
