Hi everyone!, I am trying to understand how the different timeouts actually work when using the proxy balancer directive, the idea is to define a global timeout of 10 seconds and then be able to specify a longer timeout for certain contexts, for instance:

10 seconds
https://host/files/index.html

30 seconds
https://host/files/query

300 seconds
https://host/files/submit

An example configuration is the following:

Code:
Timeout 10
ProxyTimeout 10

<Proxy balancer://lb_s>
  BalancerMember ajp://lb.host:8009 ping=10 ttl=360 timeout=20
</Proxy>

<Proxy balancer://lb_m>
  BalancerMember ajp://lb.host:8009 ping=10 ttl=360 timeout=60
</Proxy>

<Proxy balancer://lb_l>
  BalancerMember ajp://lb.host:8009 ping=10 ttl=360 timeout=600
</Proxy>

ProxyPass /files balancer://lb_s//files timeout=10
ProxyPassReverse /files balancer://lb_s/files

ProxyPass /files/query balancer://lb_m/query timeout=30
ProxyPassReverse /files/query balancer://lb_m/query

ProxyPass /files/submit balancer://lb_l//files/submit timeout=300
ProxyPassReverse /files/submit balancer://lb_l/files/submit


So how would the directive apply the timeouts?, what would take presedence?

Thanks a lot!

Johann

Take a look at some sample balancer setup examples.
Documentation can be found in the Apache docs - https://httpd.apache.org/docs/2.4/mod/mod_proxy.html

If the same thing happening if you use it without the balancer setting.

like

Code:
 <Location />
        ProxyPass ajp://localhost:8009/
        ProxyPassReverse ajp://localhost:8009/
    </Location>
