What you gurus suggest me ? i'm no way a guru, but i wrote once or twice this kind of apps .. you would like to start with RFC 1945 - HTTP/1.0 It's only 50 pages or so, and it's enough for what i see that you need. I don't see any reason to go with HTTP/1.1 - it's far more too work to do. after that, write some html "generator". for this, i think you could find some ready-written cgi libs, but i can't recommend you something specific, since i wrote my own wrappers. search in ports tree, i'm sure you will find something there. you may need to know something about sockets. i'll recommend "unix network programming", w. richard stevens, prentice hall, 1990 :), chapter 6 - berkley sockets. also you may find another good docs on the net. but if you don't know nothing about sockets, and don't want to learn, there is no problem :) you can write a small "web server" without this - just use the system's inetd. for example, see how samba's swat works (IIRC). this will allow you to start an arbitrary program when somebody connects to a specific port. the port's input/ouput will be redirected to the program's stdio, so you don't have to trouble with sockets :) stefan > > Thanks a lot for your time and cooperation. > > best regards, > Gustavo Rios. > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
