IIS 反向代理/全局 URL 重写所有站点的“/api/”文件夹

Question

I would like to reverse proxy any requests to an IIS instance for any sites where the request is in the '/api/' folder. I set up a server farm and have the reverse proxy working for everything using the '*' wildcard, but when I want to limit the scope to a RegEx it will not rewrite/proxy to the backend server. The steps I took at the IIS INSTANCE level:

1. Set up a web farm - only one server in it, machine2
2. Set up a rewrite for '*'
3. Tested against ' http://machine1/site1/api/api1 ' - it was successfully routed to machine2/site1/api/api1
4. Changed inbound rule from Wildcard to Regular Expressions
5. Changed Pattern to '. (/. /api/.*)' (without the single quotes)
6. Tested against ' http://sarjhennew10vm/site1/api/api1 '
7. Request was not routed to machine 2.

Below is a snippet from my applicationHost.config [the root of IIS].

    <rewrite>
        <globalRules>
            <rule name="ARR_Farm1_loadbalance" patternSyntax="ECMAScript" stopProcessing="true">
                <match url=".*(\/.*\/api\/.*)" />
                <action type="Rewrite" url="http://Farm1/{R:1}" />
            </rule>
        </globalRules>
    </rewrite>
    <proxy enabled="true" />

Is it possible to to a global URL re-write to the server farm for any site on the instance for specific folders?

Edit: It was answered below - I am including a picture in case others run into this. The test pattern isn't clear to me - and counters documentation found here .

Your pattern is incorrect, you can try below code, and change the rewrite url to https://Farm1/ {R: 0}

<rule name="ARR_Farm1_loadbalance" patternSyntax="ECMAScript" stopProcessing="true">
    <match url=".*(\/api\/.*)" />
    <action type="Rewrite" url="https://Farm1/{R:0}" />
</rule>
