xhWebServer

xhWebServer (eXtra Horrible) is a simple webserver written in C, using only standard and POSIX libraries. It targets Linux only.

It is not fully compliant with any standard, but should be good enough for serving HTML. ALSO REALLY INSECURE but it works!

Features

• IPv6
• accepts HTTP/0.9, HTTP/1.0 and HTTP/1.1, sends back HTTP/0.9 or HTTP/1.1
• URL decoding
• MIME type detection based on file extension
• built in and custom error pages
• custom CGI implementation (read: no existing CGI scripts work)

Building

EDIT options.h FIRST!!!!!!!! Only touch WEB_ROOT, ERROR_ROOT, SERVER_BANNER, WEB_PORT

Compile all *.c files together.

git clone https://github.com/NotBart/xhwebserver && cd xhwebserver/src && gcc -g *.c -O2 -o ../server
