title: Parsing HTTP Headers
body: <p>I've had a new found interest in building a small, efficient web server in C and have had some trouble parsing POST methods from the HTTP Header. Would anyone have any advice as to how to handle retrieving the name/value pairs from the "posted" data?</p>

  <p>I see no tangible way to retrieve the bottom line as a whole and ensure that it works every time. I'm not a fan of hard-coding in anything.</p>
