title: Git http.cookiefile configuration option not working
body: <p>The configuration option <code>git config --global http.cookiefile /&lt;absolute path&gt;/my_cookiefile</code> does not seem to have any effect on git. Having the following cookiefile :</p>
  
  <blockquote>
    <p>Set-Cookie:my_cookie=my_value; Path=/; Domain=.github.com</p>
  </blockquote>
  
  <p>The file perfectly work using directly :</p>
  
  <blockquote>
    <p>$curl  -v --cookie my_cookiefile <a href="https://github.com/my_url" rel="nofollow">https://github.com/my_url</a></p>
    
    <p>GET my_url HTTP/1.1<br>
    Host: github.com<br>
    Cookie: my_cookie=my_value</p>
  </blockquote>
  
  <p>But it has no effect with git (same curl output but no cookie header):</p>
  
  <blockquote>
    <p>$export GIT_CURL_VERBOSE=1 &amp;&amp; git clone <a href="https://github.com/my_url" rel="nofollow">https://github.com/my_url</a></p>
    
    <p>GET my_url HTTP/1.1<br>
    Host: github.com  </p>
  </blockquote>
  
  <p>git version 1.7.1</p>
  
  <p>Any idea of what could be wrong ?</p>
