It all depends on the library. If you use my code
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff

It looks like this:

==
import arsd.cgi;
void hello(Cgi cgi) {
     cgi.write("Hello, world!");
}
mixin GenericMain!hello;
==


You can build that as a cgi app to drop into any
web server, a FastCGI app to use a longer running
process on almost any webserver, or a HTTP server,
standalone.

Get cgi.d from my github then



Fast CGI C library from the internet (search for libfcgi)

or get netman.d and httpd.d and


standalone, only works on linux

There's no built in webserver class, and it's not something that 
should be in the standard library in the first place.

Why is this a pain, I don't see the problem. You've got an awesome 
solution, just because it's not in Phobos? I don't understand why people 
hate to install (it's not even installing just downloading) libs.

I think phobos should include a simple http server for testing purposes.

You can just comment out the code there (afaik it is only a custom 
formatting routine), or compile with the -d flag.

You're probably thinking of the std.date use in web.d.
This one though is just older stuff that you don't need
with the new cgi.d.

BTW the Phobos team deciding to break std.date is still

though if -property becomes the default, we'll have a
new king.

Use the newer standalone code:

http://forum.dlang.org/thread/cifekffsnaimfsvuxlrw forum.dlang.org?page=2#post-pfojnbnvhuahnyviekut:40forum.dlang.org

don't need netman.d anymore. Just use:

gdmd server.d cgi.d -version=embedded_httpd

to compile it.

cgi.d now includes a http server without needing the other

So if you just get the new cgi.d, you can:

dmd server.d cgi.d -version=embedded_httpd


without bothering with the httpd.d nor netman.d

lastSocketError is in phobos:
http://dlang.org/phobos/std_socket.html#lastSocketError

and it should work in windows and linux.

Maybe your compiler is old.

i think you've got only pure stocket library around std.socket or
