问题描述
我将 Apereo CAS 与 SAML 结合使用来验证我们的用户。我们的防火墙会阻止任何到外部的流量，因此我们使用内部代理服务器处理出站流量。
我们的 CAS 使用 Apache Tomcat 作为应用服务器，并且还配置为使用 http 代理：
export CATALINA_OPTS="$CATALINA_OPTS -Dhttp.proxySet=true -Dhttp.proxyHost=proxyhost -Dhttp.proxyPort=8080 "
export CATALINA_OPTS="$CATALINA_OPTS -Dhttps.proxySet=true -Dhttps.proxyHost=proxyhost -Dhttps.proxyPort=8080 "问题是，我认为 Apereo CAS 没有采用代理配置，我看到与外部主机的直接连接。 （不通过代理）。
具体的错误是：
