SetHandler proxy fcgi: Prevent adding the current document root (Apache Users)

Hi,

I have a short question to the Apache pro's ;)

I setup a vHost with Document pointing to /opt/data

A PHP-FPM instance is set up inside a docker container.

<FilesMatch "\.php$">
SetHandler "proxy:fcgi://127.0.0.1:9005/"
</FilesMatch>

So, Apache does the following now:

I access the web page and Apache serves every non PHP file from /opt/data - In the meantime any .php request would be sent to the proxy:fcgi.. Apache always expands the proxy request to "proxy:fcgi://127.0.0.1:9005/opt/data".

How can I stop Apache doing this? When I specify an own path like:

<FilesMatch "\.php$">
SetHandler "proxy:fcgi://127.0.0.1:9005/another/path"
</FilesMatch>

The new request becomes "proxy:fcgi://127.0.0.1:9005/another/path/opt/data":

mod_proxy_fcgi.c(995): [client 172.31.30.115:51615] AH01076: url: fcgi://127.0.0.1:9005/another/path/opt/data/index.php proxyname: (null) proxyport: 0
mod_proxy_fcgi.c(1002): [client 172.31.30.115:51615] AH01078: serving URL fcgi://127.0.0.1:9005/another/path/opt/data/index.php

Is there any option to prevent Apache doing this? ProxyPass(Match) does it but has problems here with any whitespaces, so I wanted to use SetHandler.

Any ideas?
Apache: 2.4.29

Thanks in advance!
