I added one printf() statement just to check whether readcb is called or not, but it never happens. Whenevr we do curl_easy_perform() will it be sending a GET message to Server? I have observed that some GET request goes to my test server. I am sure I am missing something and need help from you to fix it. > > > -- > > / daniel.haxx.se > ------------------------------------------------------------------- > List admin: http://cool.haxx.se/list/listinfo/curl-library > Etiquette: http://curl.haxx.se/mail/etiquette.html >
