我在 Debian 8.2 (Jessie) 和 Apache 2.4.10-10+deb8u 中设置了反向代理，其中有两个独立的虚拟主机，一个用于 http，另一个用于 https，基于以下配置：

我有几个从内部 IP 10.1.0.116 公开的 Web 服务（及其 WSDL），正如您在 Proxy* 配置指令中看到的那样，问题是我无法将传入的纯 http 流量重定向到这些 Web 服务，而且它们只使用 https 工作，所以我猜我的 VirtualHost 配置在端口 80 上肯定有问题。
更奇怪的是，当请求 URL 是这样的时：
http://HOST/telemetria-ws/frioChileTempService/
我确实收到了一个响应*，但是一个空响应，其中包含以下响应标头：
*响应似乎是 HTTPS，因为有效证书出现在 SOAP-UI SSL 信息中
但是当我将端口 80 添加到 URL 时（应该与上面相同）：
http://HOST:80/telemetria-ws/frioChileTempService/
服务器将其解释为 SSL，但使用明文连接：
Wed Feb 22 10:52:21 ART 2017:ERROR:javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
我在哪里可以得到不匹配的配置？期望的是将普通 http 重定向到 https，但不完全了解可能发生的情况。
