Hello List,

currently i use classic mod_fastcgi (fastcgiexternalserver) with php-fpm,
which is quite reliable.
A disadvantage of this setup is, that not every response-header set by
.htaccess will really send to client.
Something like this is the current setup:

<IfModule mod_fastcgi.c>
     AddHandler myphp-cgi .php
     Action myphp-cgi /cgi-fpm/php71-fpm
</IfModule>

The big advantage is, that my users are able to use addhandler by .htaccess
to choose any provided php-version.

Now i try to switch from mod_fastcgi to new recommend way of mod_proxy_fcgi

The basic variants with SetHandler are working easily:
<FilesMatch \.php$|\.php70$|\.phpx$>
     SetHandler "proxy:unix:/dev/shm/php70fpm.sock|fcgi://localhost/"
  </FilesMatch>

Now i want to use AddHandler again, so .htaccess files of my users will
automatically work former way and choose proper php-version.
Unfortunately i was not able to combine AddHandler, Action and the proxy in
a working way:

Addhandler php-mycgi .php
Action php-mycgi "proxy:unix:/dev/shm/php71fpm.sock|fcgi://localhost/"

When enabling this in global conf every request to php files results in a
400 response:
[Mon Sep 11 10:10:09.375597 2017] [core:error] [pid 23826] [client
x.x.x.x:53050] AH00126: Invalid URI in request GET /phpinfo.php HTTP/1.1

Please give me a hint to a working configuration. All my attempts were not
successful.

Action could be tricky here. Are you using php-fpm? Have you
considered allowing users to point at different sockets for diffrenent
fpm pools?

thanks for your answer. yes, i want to proxy to a socket provided by 

php-fpm. I run some different php-versions and allow my Users to choose 

fitting version by:

AddHander php70 .php
or
Addhandler php71 .php

With classical modfastcgi this is easy. Every User has its own socket 

provided by php-fpm pool-configuration and is used in VHosts of this user.

I investigated some time and found this: 

http://grokbase.com/t/apache/dev/1426dr36b5/adding-addhandler-support-for-mod-proxy

To my surprise this code is alreay present in apache 2.4.27
This is working:
Addhandler "proxy:unix:///dev/shm/php70fpm.sock|fcgi://localhost/" .php

It seems problem it is more mod_actions related and action is not 

supporting the proxy-notation. This would not be a problem for a pure 

serverside configuration.

But in this case all my users have to rewrite their .htaccess . with too 

much users in hosting this is not possible.

I have to find a way where notation like "Addhandler php71 .php" also 

works with a fcgi-proxy, so creating a basic handlername and bind this 

to a proxy action.

But unfortunately i cant achieve this on my own.

Thanks for your help.
