A web server with D

[Mengu]

Hi,

I have been interested in and learning D for a while and currently developing
a web development IDE with it. I can say that I have a middle level knowledge
that I have been trying to increase. Anyway. I want to develop a web server
for Python and Ruby web applications some months later from now,
after completing the IDE. But until then I want all my research to be
completed and I have enough knowledge that I need to develop this web server,
in addition to D and within D.

So, my two questions are these:

  1) What do I need to know in order to develop a web server, generally?
  2) What do I need to know within D to make this good enough?

Thanks everyone in advance.
