title: c read authentication from url and favicon.ico
body: <p>I'm working on a C coded server that have to reply to browsers' requests. It have to give authentication when using url like this: </p>
  
  <pre><code>http://user:pass@website/
  </code></pre>
  
  <p>but I really don't know how or where get this information on my server, because what I got when I read the request is the same that I can read when I interact with the server simply using</p>
  
  <pre><code> http://website/
  </code></pre>
  
  <p>Second question is that sometime I have this favicon.ico request from browsers.. what can I reply to the browser to say "I have not this fu*<em>*</em>* stupid icon"? :D</p>
  
  <p>I'm of course using socket for this</p>
