Setting timeout for all the ProxyPass mappings in Apache Server mod_proxy directive [closed]

Question

What I have and works:

I'm using Apache HTTPD 2.2 for proxy requests. I have multiple ProxyPass mappings:

ProxyRequests On 
<Proxy *>
AddDefaultCharset off
    Order deny,allow
    Allow from all
</Proxy>
ProxyPreserveHost Off

ProxyPass /a http://some_ip/
ProxyPassReverse /a http://some_ip/

ProxyPass /b http://some_other_ip/
ProxyPassReverse /b http://some_other_ip/

...

This works well.

What I want:

Some of my requests are taking longer, so they timed out giving me a Proxy Error - Reason: Error reading from remote server.

I want to set timeout for all of my requests. Can I do this without having to add timeout=... KeepAlive=On for every ProxyPass mapping?

I currently have something like:

ProxyPass /a http://some_ip/ timeout=1200 KeepAlive=On
ProxyPassReverse /a http://some_ip/

ProxyPass /b http://some_other_ip/ timeout=1200 KeepAlive=On
ProxyPassReverse /b http://some_other_ip/

... and i do this for all my ProxyPass mappings

Can I tell Apache in some way to add timeout and KeepAlive parameters for all the mappings? Thanks in advance.

Off topic. Try serverfault.com. – Boletus

I agree with you that it goes better in ServerFault, but there are Apache and mod_proxy related tags, are there not? My question targets the mod_proxy directive settings of Apache 2.2 Server. – Tichonn

I know, thank you for that. I managed however to find a solution by my own and I'm adding it here, maybe someone finds it useful. – Tichonn

I've managed to find a solution by my own. You can set the timeout using directly the ProxyTimeout directive of mod_proxy :

ProxyRequests On 
<Proxy *>
    AddDefaultCharset off
    Order deny,allow
    Allow from all
</Proxy>
ProxyPreserveHost Off

ProxyTimeout 1200

What is that ProxyPreserveHost for ? To setting timeout ProxyTimeout Directive isn't enough !!!! Do we have to specify all these lines to setup ProxyTimeout ? – Omegaomelet

Where are these lines added? – Yance

The directive ProxyTimeout can be placed in: server config and under virtual host. Initial question was about all of the requests made, which means global scope (server config), thus I would put it to /etc/apache2/mods-available/proxy.conf or familiar file under Apache conf dir, to keep it in order. However, in practice, it can be placed anywhere. I would also wrapped it in <IfModule mod_proxy.c></IfModule> to avoid a failure upon migration or module package removable. – Coaster
