Separating HTTP Response Body from Header in C++

I'm currently 开发者_如何学Pythonwriting my own C++ HTTP class for a certain project. And I'm trying to find a way to separate the response body from the header, because that's the only part I need to return.

Here's a sample of the raw http headers if you're not familiar with it:

HTTP/1.1 200 OK
Server: nginx/0.7.65
Date: Wed, 29 Dec 2010 06:13:07 GMT
Content-Type: text
Connection: keep-alive
Vary: Cookie
Content-Length: 82

Below that is the HTML/Response body. What would be the best way to do this? I'm only using Winsock library for the requests by the way (I don't even think this matters).

Thanks in advance.

HTTP headers are terminated by the sequence \r\n\r\n (a blank line). Just search for that, and return everything after. (It may not exist of course, e.g. if it was in response to a HEAD request.)

Do you need to roll your own? There are C/C++ libraries out there for doing HTTP, e.g. libcurl. If you need to support the full gamut of HTTP, then it's not always a simple delineation. You might also have to cater, for example, for chunked encoding.
