i've done that, and i've set the configuration per-directory, but it
seems that is have every time the same value, even if called from
different locations:

static const command_rec        kcache_directives[] =
{
    AP_INIT_TAKE1("KcacheEnabled", kcache_set_enabled, NULL,
ACCESS_CONF, "KcacheEnabled must have Off or On value"),
    AP_INIT_TAKE1("KcachePath", kcache_set_path, NULL, ACCESS_CONF,
"KcachePath must contain the path"),
    { NULL }
};


static void register_hooks(apr_pool_t* pool)
{

        /*
        * imposto i valori di default
        */
        config.enabled=FALSE;
        config.path="/var/www";

        static const char *succ[] = {"mod_proxy.c","mod_alias.c", NULL};        
    ap_hook_translate_name(kcache_handler, NULL, succ, APR_HOOK_MIDDLE);
}
module AP_MODULE_DECLARE_DATA kcache_module = {
    STANDARD20_MODULE_STUFF,
    NULL,
    NULL,
    NULL,
    NULL,
    kcache_directives,
    register_hooks
};

then i have:
in the global config
<Directory />
           KcacheEnabled Off
</Directory>
and in a specific vhost:
    <Directory "/var/www/kcache/trunk/data">
        KcacheEnabled On
        KcachePath /var/www/data
     </Directory>

finally i've added in my handler:

static int kcache_handler(request_rec* r)
{
        apr_status_t s; 

        ap_log_rerror(APLOG_MARK, APLOG_DEBUG,s,r,"KcacheEnabled = 
%i",config.enabled);
        ap_log_rerror(APLOG_MARK, APLOG_DEBUG,s,r,"KcachePath = 
%s",config.path);
        if(!config.enabled){
            ap_log_rerror(APLOG_MARK, APLOG_NOTICE,s,r,"KcacheEnabled = Off,
exiting from kcache");
        return DECLINED;
        
        }
...
...

but looking at logs it seems that KcacheEnabled is always On.

Is my approach correct?

Thanks
