How to exclude a particular folder from ASP.NET 6 on IIS and allow it to process by PHP handlers?

Question

I can deploy an ASP.NET 6 web app to IIS on Windows 2019 Server. All is working.

The default web.config is generated and exist in the root:

<system.webServer>
<handlers>
  <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
</handlers>
<aspNetCore processPath=".\TestWebApp.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
</system.webServer>

Question

I would like to have a /blog folder and I would like deploy a PHP application there. How can I explain to IIS to not pass those request to the AspNetCoreModuleV2 handler, instead pass those requests to the PHP handler? (url rewrite module is already installed)

I've ended using the <location...> element and removing the handler from the blog path.

The key is removing the handler for the blog subfolder, which can be done with the <remove>. It is possible either with using the <location...> element, or as an alternative placing a web.config to the blog subfolder, and removing the handler there.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath=".\TestWebApp.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
  <location path="blog">
    <system.webServer>
      <handlers>
        <remove name="aspNetCore" />
      </handlers>
    </system.webServer>
  </location>
</configuration>

You can create a Virtual Application under your webapp site.

The official documentation has only one paragraph describing this Virtual Application. The answers in the following posts are very detailed and will help you.
