Hi,
        The code I am running is almost in sync with the curl cvs. To handle cookies I was only using some of curl's helper functions but was setting cookie directly in the Headers. Every thing seem to work fine till I tried to do the following:

        m_Curlshare = curl_share_init();
        curl_share_setopt(m_Curlshare,CURLSHOPT_SHARE,CURL_LOCK_DATA_DNS);
        curl_share_setopt(m_Curlshare,CURLSHOPT_LOCKFUNC,dns_curl_lock_function);
        curl_share_setopt(m_Curlshare,CURLSHOPT_UNLOCKFUNC,dns_curl_unlock_function);
        curl_share_setopt(m_Curlshare,CURLSHOPT_USERDATA, &m_csCurlDNS);

        .
        .
        .
        
        void *curlhandle = curl_easy_init();
      curl_easy_setopt(curlhandle, CURLOPT_CONNECTTIMEOUT, m_lTimeout);
        curl_easy_setopt(curlhandle, CURLOPT_TIMEOUT, m_lOverallTimeout);
        curl_easy_setopt(curlhandle, CURLOPT_FILETIME, (long)true);
        curl_easy_setopt(curlhandle, CURLOPT_SHARE, m_Curlshare);

        The last call results in data->cookies being initialised. And this results in curl parsing cookies and setting them.
And while we are sending more requests in http.c Curl_http(), when we do the following things:
First we do check if someone has already set Cookie header even if data->set.cookie might be true.
  if(data->set.cookie && !checkheaders(data, "Cookie:")) {
    if(conn->allocptr.cookie)
      free(conn->allocptr.cookie);
    conn->allocptr.cookie = aprintf("Cookie: %s\015\012", data->set.cookie);
  }

Then we again try and get the cookie list:

  if(data->cookies) {
    Curl_share_lock(data, CURL_LOCK_DATA_COOKIE, CURL_LOCK_ACCESS_SINGLE);
    co = Curl_cookie_getlist(data->cookies,
                             conn->allocptr.cookiehost?
                             conn->allocptr.cookiehost:host, ppath,
                             (bool)(conn->protocol&PROT_HTTPS?TRUE:FALSE));
    Curl_share_unlock(data, CURL_LOCK_DATA_COOKIE);
  }

But this time we don't check using checkheaders?

    if(co) {
      int count=0;
      struct Cookie *store=co;
      /* now loop through all cookies that matched */
      while(co) {
        if(co->value) {
          if(0 == count) {
            add_bufferf(req_buffer, "Cookie: ");
          }
          add_bufferf(req_buffer,
                      "%s%s=%s", count?"; ":"", co->name, co->value);
          count++;
        }
        co = co->next; /* next cookie please */
      }
      if(count) {
        add_buffer(req_buffer, "\r\n", 2);
      }
      Curl_cookie_freelist(store); /* free the cookie list */
      co=NULL;
    }

Why is that?

My problem is that because I am setting the cookie header explicitly outside of curl and still want to use the share option, how do I stop curl from automatically sending cookies? Most of the sites don't mind duplicate cookies being sent in the same request but some don't work.

Thanks,
Siddhartha.
