title: Uploading file using libcurl failed. Uploading speed is zero
body: <p>Edit: This upload-file-thing is really killing me! I've no idea why this code doesn't work. It's published at libcurl-website. It's supposed to be right. Could anyone help me plz!</p>
  
  <p>I'm testing the fileupload.c from code examples found at <a href="http://curl.haxx.se/libcurl/c/fileupload.html" rel="nofollow">http://curl.haxx.se/libcurl/c/fileupload.html</a>
  However, I can't upload a txt to server. 
  I replaced the origin code</p>
  
  <pre><code> fd = fopen("debugit", "rb"); /* open file to upload */ 
   /* upload to this place */ 
   curl_easy_setopt(curl, CURLOPT_URL,
                   "file:///home/dast/src/curl/debug/new");
  </code></pre>
  
  <p>to</p>
  
  <pre><code>  fd = fopen("c:\\\testupload.txt", "rb"); 
    curl_easy_setopt(curl, CURLOPT_URL,
                   "http://xx.xx.xx.xx/dir/test.txt");
  </code></pre>
  
  <p>Here's the output.  See bottom: Speed: 0.000 bytes/sec during 0.120 seconds. </p>

    &lt;ul&gt;  &lt;li&gt;The directory or file specified does not exist on the Web server.&lt;/l
  i&gt;      &lt;li&gt;The URL contains a typographical error.&lt;/li&gt;        &lt;li&gt;A custom fil
  ter or module, such as URLScan, restricts access to the file.&lt;/li&gt; &lt;/ul&gt;
   &lt;/fieldset&gt;
  &lt;/div&gt;
  &lt;div class="content-container"&gt;
   &lt;fieldset&gt;&lt;legend&gt;Things you can try:&lt;/legend&gt;
    &lt;ul&gt;  &lt;li&gt;Create the content on the Web server.&lt;/li&gt;  &lt;li&gt;Review the browser U
  RL.&lt;/li&gt;        &lt;li&gt;Create a tracing rule to track failed requests for this HTTP
   status code and see which module is calling SetStatus. For more information abo
  ut creating a tracing rule for failed requests, click &lt;a href="http://go.microso
  ft.com/fwlink/?LinkID=66439"&gt;here&lt;/a&gt;. &lt;/li&gt; &lt;/ul&gt;
   &lt;/fieldset&gt;
  &lt;/div&gt;
  
  
  &lt;div class="content-container"&gt;
   &lt;fieldset&gt;&lt;legend&gt;Links and More Information&lt;/legend&gt;
    This error means that the file or directory does not exist on the server. Crea
  te the file or directory and try the request again.
