hi,

Thanks to all for kind reply.

As per mailing discussion. I added user agent by following way.

Started wireshark utility and tried following on terminal

>curl "http://mt1.google.com/mt?x=92&y=200&zoom=8" -o "file1"

in wireshark, i found

User Agent : curl/7.19.0 (arm-unknown-linux-gnueabi) libcurl/7.19.0
OpenSSL/0.9.8g zlib/1.2.3

Now, in my program i added

 curl_easy_setopt(curl,CURLOPT_USERAGENT,"curl/7.19.0
(arm-unknown-linux-gnueabi) libcurl/7.19.0 OpenSSL/0.9.8g zlib/1.2.3\r\n");

  struct curl_slist* headers = 0;
  headers = curl_slist_append(headers, url);
  curl_easy_setopt(curl, CURLOPT_HEADER, headers);

with above option, Now i am able to download requested file, with following
reply
