I already tested a bit with rewrite bit my and your variant is not working. If I set your variant the result is:


mod_proxy_fcgi.c(995): [client 172.31.30.115:54624] AH01076: url: fcgi://127.0.0.1:9005//opt/data/another proxyname: (null) proxyport: 0, referer: http://nextcloud.jki.intern/

(Even the "/path" from "/another/path" is truncated :O )

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.

The high level issue/cause here is that the core of the server will
map URL's to Filenames and the tracked filename is what proxy_fcgi
knows to request.

How about something in this neighborhood (in vhost/global scope) which
sets r->filename and the handler together w/ rewrite:

RewriteEngine ON
RewriteRule \.php$ /another/path/$0 [H=proxy:fcgi://127.0.0.1:9005/]
