Add a header to a cppnet-lib response object - c++

Question

I would like to add a header to a cppnet-lib basic_response object. However, I am getting compilation errors.
I can add a header to a basic_request as follows which compiles ok:
boost::network::http::basic_request<boost::network::http::tags::http_server> request;
request << header("test", "test");
However, doing the same for a response object as follows receives a compilation error:
boost::network::http::basic_response<boost::network::http::tags::http_server> response;
response << header("test", "test");
Compilation error:
'headers_container_type': the symbol to the left of a '::' must be a type (header.hpp)
'value_type': is not a member of boost::network::http::basic_response<boost::network::http::tags::http_server> (header.hpp)
syntax error: missing ';' before identifier 'value_type' (header.hpp)
This would suggest that this isn't possible on a response object, but following the following page seems to suggest it is. I'm obviously going wrong somewhere!
Documentation: http://cpp-netlib.org/0.8/reference_http_response.html
My environment is:
Visual Studio 2013 (building as Release)
Boost 1.55
cppnet-lib: 0.11.0
Any help would be very much appreciated! Thanks.

First, I think you're using the wrong documentation since you're using version 0.11.0 (I suggest you use 0.11.1, which has a lot of bug fixes on top of 0.11.0). Here's the link you actually want for the 0.11.0 documentation:
http://cpp-netlib.org/0.11.0/reference/http_server.html#response-object
Second, you'd want to add headers directly to the response object's headers member. No need to use functions to do this:
struct my_server {
void operator(server::request const& req, server::response & res) {
// do something with the request and/or response
res.headers.push_back(server::response::header("Name", "value"));
// do more things
}
// ...
};
