@glasslion "WSGI 本来就不支持持久化连接和服务端推送"

对 WSGI 一知半解, 从文档看: https://www.python.org/dev/peps/pep-0333/

> Applications and middleware are forbidden from using HTTP/1.1 "hop-by-hop" features or headers, any equivalent features in HTTP/1.0, or any headers that would affect the persistence of the client's connection to the web server. These features are the exclusive province of the actual web server, and a server or gateway should consider it a fatal error for an application to attempt sending them, and raise an error if they are supplied to start_response() . (For more specifics on "hop-by-hop" features and headers, please see the Other HTTP Features section below.)

单看文档感觉使用 WSGI 在约束 HTTP Server 的情况下, 它是能够保证持久化连接的? 所以并不算 WSGI 的问题, 算是 uWSGI 在多 worker 情况下没法满足 wsgi 的约束?
