Hi,

I need a hook function that looks at pre_request (also post) phase
after the rewriting phase of worker's  URL (e.g.,
http://worker2.com/test.php) to use the name of the worker for my own
propose.

I tried to put this way:

static const char * const aszPre[]={ "mod_proxy_balancer.c", NULL };
proxy_hook_pre_request(my_pre_request, aszPre, NULL, APR_HOOK_LAST);

But the proxy_pre_request function in mod_proxy_balance returns OK,
and my function is nerver called. There's a better way to do this
without touching in apache internal source-code?

Putting in more details... look at this log information:

*** (ALSO I NEED A POST HOOK HERE, i think this is easier... )

Thanks in advance.
