Your code seems rather nice.

That said, here are some remarks of a purely stylistic nature :-) :

- You can use "foreach" instead of "for" to simplify your loop statements over arrays and other collections:
    auto array = [1, 2, 3];
    foreach (item; array) {
        writeln (item);

  foreach can also support indexed iteration of your items:
    auto array = ["a", "b", "c"];
    foreach (index, item; array) {
        writefln ("%d: %s", index, item);

and if you just want to iterate a certain amount of time, you can use ranges:
    foreach (index; 1..100) {
        writeln (index);

- You don't have to put each class in a different file: you still can do if you prefer it that way.

- I tend to prefer to have class members of same visibility grouped together under a "public:", "protected:" or "private:" block, either using the colon or the braces instead of always specifying the visibility - this kind of help me better understand what will be useful when using the class.

- Associative arrays can be initialized with literals, so instead of having lots of:
   status_message[100] = "Continue";
   status_message[101] = ...
   status_message[505] = "HTTP Version not supported";

 you can use:
   status_message = [
       100: "Continue",
       101: ...
       505: "HTTP Version not supported"

 which I find more concise.

- You can also use unified function calls:
  instead of: to!string(port)
  you can do:!string
  the latter having a more "English" feel when reading.

Again, these are purely stylistic considerations, D's flexibility allows you to choose from many styles.

On a design standpoint, I would have preferred a delegate for the processRequest() method instead of requiring the users to derive from the WebServer class - on second thought, that may too be a stylistic issue :-) .

Also related: I have started to write some high level bindings to the Mongoose embedded webserver library, written in C (using Jacob Carlsberg's dstep for the low level bindings). The source code is available here: .
You may find some stuff to reuse or get inspiration from for your server.

Adam Ruppe also has a lot of interesting tools beyond the basic web serving that you may get interested in (

Because I have a personal project based on a custom web server, and I
couldn't find one implemented in D(excepting vibe.d), I started to
implement some web server classes in D with the hope that my work will
be useful to someone else as well. If you are interested in this
project, or if you want to contribute to it, here is the link to the git

Also, I don't have a lot of experience with D and I would apreciate if
someone would like to spare some time for a code review for my work.
