Bash web server and client

Do not actually use this for anything. It is a simple bash scripting example.

Tips

• both the client and server should be sending CRLF rather than just LF
• the current implementation does not fully follow this requirement
• access to parent directory .. and shell escapes is not done.
• test first with just netcat as the client or netcat as the server
• once that part is working, use curl or wget as a client.
• some versions of netcat do not allow the -e parameter.
