You can retrieve some statistics using curl_easy_info and you can capture traces with CURLOPT_DEBUGFUNCTION. But, that won't include SSL, TCP, IP or 3G overhead. Most of that is tracked at the OS level on the network interface (see ifconfig). > Currently my data usage using curl_http post is 3MB per day.

It could easy use that much if it's sending just a 10 byte payload once every minute from the overhead of a full SSL handshake plus an additional authentication handshake each time. >>> Dan ------------------------------------------------------------------- List admin: https://cool.haxx.se/list/listinfo/curl-library Etiquette: https://curl.haxx.se/mail/etiquette.html
