Comment 2 for bug 1509083

we confirm this behavior with:
mod_proxy_fcgi
mod_proxy
apache event mpm
on latest stable apache 2.4.6

we are using:

(we tried both inside and outside virtualhost: )
<Proxy fcgi://socket=%2fdev%2fshm%2ffpm-php.sock>
  ProxySet timeout=3600
  ProxySet connectiontimeout=3600
</Proxy>

ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://socket=%2fdev%2fshm%2ffpm-php.sock/mobilnet.sk/$1 timeout=3600 connectiontimeout=3600

OR
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^/?(.*\.php)$ fcgi://socket=\%2fdev\%2fshm\%2ffpm-php.sock/path/$1 [P,L]

but none of them accepts the timeout:
[proxy_fcgi:error] (70007)The timeout specified has expired: [...] AH01075: Error dispatching request to:
