Here is an advanced PHP question. Can anyone think of a way to detect

If you are using Apache and can recompile the SAPI module, you can add
the following function to php_functions.c:

/* {{{ proto integer apache_get_bytes_sent(void)
   Get the number of bytes actually sent */
PHP_FUNCTION(apache_get_bytes_sent)
{
	php_struct *ctx;
	ctx = SG(server_context);
	RETURN_LONG(ctx->r->bytes_sent);
}
/* }}} */


If TCP/IP guarenteed delivery is to be believed, then that should be
the exact number of bytes received (but not necessarily saved) by the
client.


Here is my hosting provider's configuration:
apache_get_version: Apache/1.3.33 (Debian GNU/Linux)
   mod_throttle/3.1.2 mod_ssl/2.8.22 OpenSSL/0.9.7d
php_sapi_name: apache

I am unfamiliar with PHP internals and how they interact with the web server. Will that only work on Apache 2 and with sapi as "apache2filter" or "apache2handler"? I don't think I can recompile the SAPI module, but I could build my own module and have my hosting provider install it. Is it possible to add such a function in a custom module? If it is too hard, then I will just go the low-tech route (polling the log file).

Thanks.
