Dean,
I got it to work!

Here's the code that works:

// These are my defs for namespace & server type
namespace http = boost::network::http;
typedef http::server<CgiServer> Server;


http::request_header<http::tags::http_server> content_type =
{"Content-Type", "application/vnd.google-earth.kml+xml"};

// set message in response
response = Server::response::stock_reply(Server::response::ok, kml_string);

response.headers.push_back( content_type );

Thanks for your help!
