Sunday Webserver

Der Sunday Webserver ist ein kleiner multithreaded Webserver, den ich an
einem langweiligen Sonntagnachmittag programmiert habe um die TCP/IP
Programmierung zu lernen.

Im Moment ist seine einzige Funktion die Ausgabe einer einzigen
Webseite, die statisch einkompiliert ist. Dank seiner multithre
aded Implementation kann er diese aber gleichzeitig an beliebig viele
Clients senden.

Sunday Webserver Demopage

Kompilieren:
gcc -O3 -o sunday sunday.c -lpthread
