问题 I have a PHP websocket server (https://github.com/lemmingzshadow/php-websocket/). When an user connects, I want to set/get some session data. The problem is that I can't use $_SESSION because if I do that, instead of clients' session I get the session of my websocket server. I have managed to get clients' SESSID: private function handshake($data) { $this->log('Performing handshake'); if(preg_match("/PHPSESSID=(.*?)(?:;|\r\n)/", $data, $matches)){ $sessid = $matches[1]; } /* Do handshake */ }

Why don't ASP.Net handlers support session by default

由 别等时光非礼了梦想. 提交于 2019-12-12 04:38:18
问题 I understand that in order for a ASP.Net handler to support session state you need to implement both IHttpHandler and IRequireSessionState , but why isn't session state provided by default?
