IIS 8.5 및 URL 재작성 2.0에서 웹소켓 역방향 프록시가 가능합니까?

Question

IIS 뒤에 Java 앱 서버로 Tomcat을 설치했습니다. 다음 규칙을 사용하면 정적 페이지를 잘 다시 작성할 수 있지만 아쉽게도 웹소켓 연결은 설정되지 않습니다.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <webSocket enable="false"/>
        <rewrite>
            <rules>
                <rule name="Redirect HTTP to HTTPS" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{HTTPS}" pattern="^OFF$" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}/foo/{R:1}" redirectType="SeeOther" />
                </rule>
                <rule name="Redirect from IIS to Tomcat" stopProcessing="true">
                    <match url="(.*)" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{CACHE_URL}" pattern="^(.*)://" />
                    </conditions>
                    <action type="Rewrite" url="{C:1}://tomcat.contoso.com/foo/{R:1}" />
                </rule>
            </rules>
            <outboundRules>
                <rule name="Redirect from Tomcat to IIS" preCondition="ResponseIsHtml">
                    <match filterByTags="A, Form, Img" pattern="^(.*)://tomcat.contoso.com/foo/(.*)" />
                    <action type="Rewrite" value="{R:1}://apps.contoso.com/foo/{R:2}" />
                </rule>
                <preConditions>
                    <preCondition name="ResponseIsHtml">
                        <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/html" />
                    </preCondition>
                </preConditions>
            </outboundRules>
        </rewrite>
    </system.webServer>
</configuration>

이거 성공하신 분 계신가요? URL 재작성은 웹소켓(ws:// & wss://) 역방향 프록시도 지원합니까?
