How to parse an HTTP request in C ++

I am trying to write a small C ++ web server that handles GET, POST, HEAD requests. My problem is that I don’t know how to parse headers, message body, etc. He listens to the socket, I can even write stuff in the browser just fine, but I'm wondering how can I do this in C ++.

Afaik's standard GET / POST request should look something like this:

GET /index HTTP/1.1
Host: 192.168.0.199:80
Connection: keep-alive
Accept: */*
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.22 (KHTML, like Gecko)     Chrome/25.0.1364.97 Safari/537.22
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

this is the message body

All lines end with '\ r \ n'.

Should I just split the request into "\ n" and trim them (and if so, how)? Also how to process files in post data?

But if this is not just a hobby project, and you don’t want to do a really big task, you should use either Apache if you need a web server that you need to expand, or tntnet if you need a C ++ web environment, or cpp-netlib if you need C ++ network stuff.
