title: Recommendation for a HTTP parsing library in C/C++
body: <p>I am looking for HTTP parsing library for C/C++.
  I have looked curl library, but it seems it is a http client library. 
  I am looking for a library which parses HTTP header (e.g. a way to
  get the query string, get cookie, get request url, get Post Data)? </p>
  
  <p>Thank you.</p>
