see http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypass should
be interesting, configuration changed from 2.0.x
"Connection pool worker retry timeout in seconds. If the connection pool
worker to the backend server is in the error state, Apache will not
forward any requests to that server until the timeout expires. This
enables to shut down the backend server for maintenance, and bring it
back online later."

Hello,
Below is an e-mail I've sent some while ago. I didn't receive an
answer yet. Maybe this isn't the right place for asking this question.
Perhaps its something for the devel list.
Any comment would be kindly appreciated!!

Hi,
I've a proxy setup with Apache2.2.3 and mod_proxy.
It often happens that the connection to the backend server fails:
[error] (110)Connection timed out: proxy: HTTP: attempt to connect to
xxx.xxx.xxx.xxx:xxx (host.example.com) failed
When this happens the worker is disabled for a while
[error] ap_proxy_connect_backend disabling worker for (host.example.com)
Usually the worker keeps disabled for 1 min. During that time I see the
following errors in my logs:
[error] proxy: HTTP: disabled connection for (host.example.com)
The Clients receive a 503 Service Unavailable error, but when going
directly to the backend server (not passing the reverse proxy) there is
nothing wrong.
Is this a normal behavior?
Is it possible to shorten the time the worker is disabled?
Can somebody point this out for me?
Kind regards,
Philip Brusten
