Apache 服务器：通过 mod_proxy_wstunnel 实现反向代理和 websockets

我的 Web 套接字和反向代理 apache 出了点问题，我已升级到最新版本 2.4.5 并加载了模块 mod_proxy_wstunnel。

httpd.conf：

     <VirtualHost *:80> 
ServerAdmin webmaster@localhost 
ServerName www.toto.fr 
ServerAlias toto.fr


    ProxyPass /my_app  http://1X.X.X.1:8080/my_app 
    ProxyPassReverse /web_pmr  http://1X.X.X.1:8080/my_app 
    ProxyPassReverseCookiePath /my_app / 
    ProxyPassReverseCookieDomain localhost my_app 
    ProxyRequests off 
    ProxyTimeout 15

        #WEBSOCKETS


        ProxyPass /my_app/BasicWebsocketServlet ws://1X.X.X.1:8080/my_app/BasicWebsocketServlet retry=0 
    ProxyPassReverse /my_app/BasicWebsocketServlet ws://1X.X.X.1:8080/web_pmr/BasicWebsocketServlet retry=0


ErrorLog "logs/my_app_error.log" 
LogLevel debug 
CustomLog "logs/my_app_access.log" combined 

<Proxy *>
              Order deny,allow
              Allow from all 
</Proxy> 
</VirtualHost>

当我在本地 URL 中测试时，websockets 正在运行，但使用反向代理 apache 时，tomcat 日志中没有任何痕迹。

已加载模块列表：

谢谢。

路径后面必须添加斜杠，因为必须将 Web 套接字请求处理为 GET 请求（httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypass）

就像是：

ProxyPass        /my_app/BasicWebsocketServlet/ ws://1X.X.X.1:8080/my_app/BasicWebsocketServlet/ retry=0
ProxyPassReverse /my_app/BasicWebsocketServlet/ ws://1X.X.X.1:8080/web_pmr/BasicWebsocketServlet/ retry=0
