First I'd like to thank you very much Joe for help...

I have a "begineer" question:

*3) allow apache to handle the rest of the request*. Is that mean return
1???? because when I tried this I had an error...and when I tried return OK
I had nothing...

that's my code:

*static int my_module_handler (request_rec *r) {
 char *url = apr_pstrdup(r->pool,"http:\\10.12.23.5\irj\test");
    r->filename = apr_pstrcat(r->pool, "proxy:", url, NULL);
    return 1;
}

static void **my_module**_hooks(apr_pool_t *pool){
    ap_hook_handler(**my_module**_handler, NULL, NULL, APR_HOOK_FIRST);
   }

module AP_MODULE_DECLARE_DATA **my_module**_module = {
    STANDARD20_MODULE_STUFF,
    NULL,
    NULL,
    auth_chorus_config,
    NULL,
    **my_module**_cmds,
    **my_module**_hooks
};*

Thanks
