@TeLiXj ForProxyPassMatch we have a sentence below the config example talking about a subpath of the document root:

When you run your Symfony application on a subpath of your document root,
the regular expression used inProxyPassMatch directive must be changed
accordingly

Do we need something similar forSetHandler?

I couldn't test this tip with ProxyPassMatch, but now with SetHandler I created a php file with phpinfo() on a subfolder of my web folder and I can see "Server API FPM/FastCGI "... it works without any modification in SetHandler

Thank you@TeLiXj. In this case it makes sense to move the description for the modifiedProxyPassMatch description to a comment.

Great attention to detail on this :). Thanks@xabbuh!
