hi,

I tried following url on my terminal as

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

it downloads file. before that i have already set http proxy.

now i am tring same url in my program using libcurl functions.

it gives me following error.

-------------------------------------------------------------------------------------------

* About to connect() to proxy 172.18.1.16 port 80 (#0)
* Trying 172.18.1.16... * connected
* Connected to 172.18.1.16 (172.18.1.16) port 80 (#0)

----------------------------------------------------------------------------------------------

what i am thinking if curl on terminal can download file, then my program
should do.

correct me if i am wrong.

following seeting i am doing

  curl_global_init(CURL_GLOBAL_ALL);
  curl = curl_easy_init ();
  curlinfo = curl_version_info(CURLVERSION_NOW);
  curl_easy_setopt(curl,CURLOPT_VERBOSE,TRUE);
  curl_easy_setopt(curl, CURLOPT_AUTOREFERER, 1);
  curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1);
  curl_easy_setopt(curl, CURLOPT_MAXREDIRS, 10);
  ret_code = curl_easy_setopt(curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
  printf("\n curl_easy_setopt [ret_code] : %d\n",ret_code);
  curl_easy_setopt(curl, CURLOPT_PROXYTYPE,CURLPROXY_HTTP);
  curl_easy_setopt(curl, CURLOPT_PROXY, "http://172.18.1.16:80");
  curl_easy_setopt(curl, CURLOPT_DNS_CACHE_TIMEOUT, 60 * 5); // 5 minutes
  curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0);
  curl_easy_setopt(curl, CURLOPT_FILE,fp);

what parameters i am missing to add.
