IIS Equivalent of "proxy_set_header X-Forwarded-Proto https;" - iis

Question

What is the IIS equivalent of this configuration in NGINX?
proxy_set_header X-Forwarded-Proto https;
I am running JetBrains YouTrack on Windows server, using IIS as a terminating SSL proxy, and get this error when trying to log in:
HTTP ERROR 405
Problem accessing /hub/auth/login. Reason:
HTTP method POST is not supported by this URL
Powered by Jetty://
My web.config looks like this:
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Reverse Proxy" patternSyntax="ECMAScript" stopProcessing="true">
<match url="(.*)" />
<!-- Redirect all requests to non-HTTPS site. -->
<action type="Rewrite" url="http://my.youtrack.site/{R:1}" logRewrittenUrl="true" />
</rule>
</rules>
</rewrite>
<handlers>
<clear />
<!-- No other handlers required. Must clear them otherwise ASP.NET might try to intercept *.svc paths etc. -->
<add name="Rewrite" path="*" verb="*" modules="RewriteModule" resourceType="Unspecified" />
</handlers>
</system.webServer>
</configuration>
I am trying to follow the solution from this source: https://confluence.jetbrains.com/display/YTD65/Linux.+JAR+in+Nginx+Web+Server, but for IIS

I was able to add X-Forwarded-Proto header to all requests forwarded by Application Request Routing using the following script:
Set-WebConfiguration -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.webServer/rewrite/allowedServerVariables" -Value (#{name="HTTP_X_FORWARDED_PROTO"})
Set-WebConfiguration -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.webServer/rewrite/globalRules" -value #{name='ForwardedHttps'}
Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.webServer/rewrite/globalRules/rule[#name='ForwardedHttps']/serverVariables" -name "." -value #{name='HTTP_X_FORWARDED_PROTO';value='https'}
Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.webServer/rewrite/globalRules/rule[#name='ForwardedHttps']/conditions" -name "." -value #{input='{HTTPS}';pattern='On'}
In order to make code handle HTTP/HTTPS redirects correctly the following configuration settings may need to be set as well:
Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.webServer/proxy" -name "preserveHostHeader" -value "True"
Set-WebConfigurationProperty -pspath 'MACHINE/WEBROOT/APPHOST' -filter "system.webServer/proxy" -name "reverseRewriteHostInResponseHeaders" -value "False"
