Try

if (condition) {
  ...
  return OK;
} else {
  return DECLINED;
}

and make sure your handler runs before mod_proxy's:

static const char *succ[] = {"mod_proxy.c", NULL};
ap_hook_handler(&your_handler, NULL, succ, APR_HOOK_MIDDLE);

Then put a ProxyPass in your conf:

<Location /your_url>
    ProxyPass http://www.google.it/ keepalive=On
</Location>

Also make sure you do not check on r->handler. Even if you set 
"SetHandler your_handler", ProxyPass will overwrite it with "proxy-server".
