Re: [users@httpd] Re: Dynamic refreshing of Proxy Rules

[Aman Raheja <araheja@xxxxxxxxxxxxxx>]

to have apache re-read the config, the other way is
/bin/kill -HUP `cat <path-to-pid-file>
and there's isn't a way for it to only reload the proxy changes or just 
a part of the config and it is questionable why would apache have a way 
to only reload a part of the config. No reason to support that.
