Hi all,

            The following is the code I returned to get the HTTP Header
and the HTTP content.

But the problem is,

1. If I set callback functions to get header, using
CURLOPT_HEADERFUNCTION and to get content using CURLOPT_WRITEFUNCTION,
only one callback function is getting executed.

2. If I set CURLOPT_HEADER as 1, then only the header part
(HTTP/1.1 200 OK) is coming in the CURLOPT_WRITEFUNCTION registered
callback.

So, please anyone see my following code and help me to get the HTTP
HEADER and also the CONTENT

Get()

{

            CURL *curl;

            CURLcode res;

            char* data=NULL,*data1=NULL;

            char* match = "Etag:";

            curl = curl_easy_init();

            if(curl) {

                        curl_easy_setopt(curl,
CURLOPT_URL,"xcap.example.com ");

                        curl_easy_setopt(curl,
CURLOPT_FOLLOWLOCATION,1);

                        curl_easy_setopt(curl, CURLOPT_HTTPGET,1);

                        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION,
read_callback);

                        curl_easy_setopt(curl, CURLOPT_WRITEDATA,
&data);

                        curl_easy_setopt(curl, CURLOPT_VERBOSE, 0);

                        curl_easy_setopt(curl, CURLOPT_HEADER,1);

                        curl_easy_setopt(curl, CURLOPT_HEADERFUNCTION,
get_xcap_etag);

                        curl_easy_setopt(curl, CURLOPT_HEADERDATA,
&data1);

                        res = curl_easy_perform(curl);

            }

}

Callback functions.

size_t get_xcap_etag( void *ptr, size_t size, size_t nmemb, void
**userp)

{

 if(size*nmemb < 1)

            return 0;

  if (ptr)

  {

              *userp = malloc (strlen((char *)ptr) + 1);

              strcpy (*userp, (char *)ptr);

              return 1;

  }

  return -1;

}

static size_t read_callback(void *ptr, size_t size, size_t nmemb, void
**userp)

{

  if(size*nmemb < 1)

    return 0;

  if (ptr)

  {

              *userp = malloc (strlen((char *)ptr) + 1);

              strcpy (*userp, (char *)ptr);

              return 1;

  }

  return -1;

}

Thanks & Regards,
