我需要在IIS 7+Coldfusion 9上上传文件，它将文件上传到framesocket.com，framesocket.com使用servlet和websocket，但我看到连接终止，错误1006。我看到了，这个servlet在Tomcat 8.09上运行得非常完美。但当我在IIS+Coldfusion上运行它时，它不起作用。交易在Coldfusion 9+Webspcket中进行？感谢您的帮助除了概念验证之外，我对web套接字的了解不多，但从这篇博客文章的内容来看，您需要一些在CF9上运行的非开箱即用的东西，web套接字才能工作。请记住，默认情况下，CF9不会在Tomcat上运行，它是JRun。因此，您对在TOmcat上运行的东西的测试不一定有意义。对不起，除此之外帮不了什么忙。
