std.socket is too low level for serving webpages. It just provides the means to talk on the network, but doesn't do any application protocols like http.
I've written a little http server in D, but it uses linux system calls instead of std.socket, so it only works on linux. http://arsdnet.net/dcode Check out httpd.d and netman.d in there. Also, my cgi.d can work together with them to serve web apps through the mini web server. But as you can see, a lot of the code is parsing and writing http. When you go to a web site, your browser sends something like this to the server: GET /index.html HTTP/1.1 Host: mysite.com Then, the server replies: HTTP/1.1 200 OK Content-Length: 13 Content-Type: text/plain Connection: close Hello, world! Then the connection is closed and the get is complete.
