I made a simple web server in Ruby using the Mongrel gem. It works great for files in a single directory, but I run into some path issues when inside a directory.

Lets say we have 2 files in a directory named "dir1", "index.html" and "style.css". If we visit http://host/dir1/index.html, the file is found, but style.css isn't because it's trying to load "style.css" from http://host/style.css instead of inside the directory.

index.html is trying to load style.css as if its in the same directory as itself.

<link href="style.css" rel="stylesheet" type="text/css" />

I can get the file if I enter the full path of style.css: /dir1/style.css but it doesn't seem to remember it's already inside a directory and that no path before a filename should serve from the current directory.

This is the ruby code im using to serve out files.

require 'rubygems'
require 'mongrel'

server = Mongrel::HttpServer.new("0.0.0.0", "3000")
server.register("/", Mongrel::DirHandler.new("."))
server.run.join
