Subject[RFC, PATCH] khttpd until-now private patch
Date
Hello,
this is my first try to submit a patch.

I have looked through khttpd and saw some MIME types but others
haven't been there, especially I saw that one could not serve
plain binary files. So I have added some MIME types... a /proc
interface was nice, though.

Secondly I have allowed myself to update the RFC821 date-time
handling. You do not need to add the day of the week field,
and according to RFC282(1,2) UTC should be served ad +0000
(or -0000 if it is not 100% secure that it really is UTC,
or if UTC is not local time, however I decided to do +0000).

Feel free to correct me if I am wrong, if not I would like
to see this in the stock kernel.
