Resolved Unable to configure IIS FastCGI Settings for PHP through panel.ini

[JanReilink]

I'm currently using Plesk Obsidian PANEL_18_0_40_WIN. In Plesk Obsidian's docs we find:

By editing the panel.ini file, you can make the following changes to this scenario:

• Determine what predefined values a PHP parameter can take.
• Change the default value for a PHP parameter.
• Forbid specifying custom values for PHP parameters.

Following the documentation, I set into my panel.ini file:

[php]
settings.performance.memory_limit=512
settings.fastCgi.maxInstances=10
settings.fastCgi.instanceMaxRequests=10000
settings.fastCgi.activityTimeout=89
settings.fastCgi.requestTimeout=180

But unfortunately this is not picked up by Plesk when I create a new subscription and Plesk registers a new FastCGI application.

Using AppCmd I can determine currently configured values:

PS C:\Users\janreilink> appcmd list config "plesk.php.example.org" /section:FastCGI
<system.webServer>
  <fastCgi>
    <application fullPath="D:\pleskinstall\admin\engine\php-cgi.exe" arguments="-dauto_prepend_file=auth.php" maxInstances="12" idleTimeout="1800" activityTimeout="3600">
      <environmentVariables>
      </environmentVariables>
    </application>
    <application fullPath="D:\pleskinstall\Additional\PleskPHP80\php-cgi.exe" arguments="-d siteId=8">
      <environmentVariables>
        <environmentVariable name="TEMP" value="D:\www\plesk.php.example.org\tmp" />
        <environmentVariable name="TMP" value="D:\www\plesk.php.example.org\tmp" />
      </environmentVariables>
    </application>
  </fastCgi>
</system.webServer>

On a non-Plesk webserver, where I configured FastCGI settings, this is the result:

PS C:\Users\janreilink> appcmd list config "wordpress.example.net" /section:FastCGI
<system.webServer>
  <fastCgi>
    <application fullPath="d:\php\default\php-cgi.exe" stderrMode="ReturnStdErrIn500" maxInstances="10" activityTimeout="89" requestTimeout="180" instanceMaxRequests="10000" protocol="NamedPipe" flushNamedPipe="false">
      <environmentVariables>
        <environmentVariable name="PHP_FCGI_MAX_REQUESTS" value="10001" />
        <environmentVariable name="PHPRC" value="d:\php\default\php.ini" />
        <environmentVariable name="OPENSSL_CONF" value="d:\php\default\extras\ssl\openssl.cnf" />
      </environmentVariables>
    </application>
  </fastCgi>
</system.webServer>

Either I'm doing something wrong, the documentation is wrong, or I hit a bug.

Figured it out, I have to reconfigure the default settings, with `.default` added to the parameters in `panel.ini`:

settings.fastCgi.maxInstances.default=10
settings.fastCgi.instanceMaxRequests.default=10000
settings.fastCgi.activityTimeout.default=89
settings.fastCgi.requestTimeout.default=180
settings.fastCgi.queueLength.default=10
