I am running Server and Client on same machine and they are communicating on loopback. As per the document CURLOPT_URL is mandatory for curl_easy_perform, I have mentioned it and have given localhost port 4433, where server is listening. Client is binded on port 4434, yesterday Daniel mentioned that CURLOPT_INTERFACE is used for client to bind on local port, so my client is binded on port 4434. > > > curl_easy_setopt(ctx, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1); >> > > HTTP 1.1 is default. > > size_t write_data( void *buffer, size_t size, size_t nmemb, void *userp ) >> { >> int segsize = size * nmemb; >> >> CURL *ctx = (CURL*)userp; >> printf("\nCurl object address is:%p",ctx); >> CURLcode ret; >> >> curl_easy_setopt( ctx1 , CURLOPT_READDATA ,ctx); >> curl_easy_setopt( ctx1 , CURLOPT_READFUNCTION , readcb ); >> curl_easy_setopt(ctx1, CURLOPT_CUSTOMREQUEST, "GET") ; >> *int ret = curl_easy_perform(ctx1);* >> > > You can't call curl_easy_perform() from within the write callback on the > same handle.

In this case how will I send second GET request, if I am not wrong then I need to call curl_easy_perform() every time I need to send a GET request, is it right??? By providing readcb, will I be able to send GET with my custom data??? > -- > > / daniel.haxx.se > > ------------------------------------------------------------------- > List admin: http://cool.haxx.se/list/listinfo/curl-library > Etiquette: http://curl.haxx.se/mail/etiquette.html >
