[users@httpd] DNS lookup cached
I'm using Apache as reverse proxy to redirect request inside a LAN.
I'm trying to dynamically change the address to which forward request
through Apache.
In my configuration file I use something like:
<location /dynlocation/>
ProxyPass http://dynlocation/
ProxyPassReverse /
</location>
The DNS lookup is resolved reading the hosts file (it's a window system).
10.0.0.1 dynlocation
I thought that chancing the hosts file at runtime would have made the trick,
i.e. writing:
10.0.0.2 dynlocation
but it seems that Apache is caching the IP and keeps on sending requests to
10.0.0.1
I cannot restart Apache every time I need a different IP.
Does anybody know how to clean that DNS cache or has a different idea to
solve this problem?
Thanks,
Diego

Any hint on this topic?
Can anybody try to replace this behavior?
It's easy.

I performed also a ipconfig/flushdns to clean windows cache, but it didn't
work.
In Apache configuration files I use the DNS name 'dynlocation', but I look
at the error logs that Apache produces when the host can not be reached I
see that it is using the old IP.

I doubt apache caches the IP. I guess it's windows who is caching the IP,
check that possibility first.
