Static files server

Read the guideline before start

Create a server that will return files using a part of the path after /file/.

Rules

• Return only files from a folder public
• There should not be access to any other files
• Return 404 status for non existent files (with text/plain content type)
• If the pathname does not start with /file/ return a message with a hint how to load files (text/plain)
• If the pathname is exactly /file return a hint message (text/plain)
• If the pathname contains ../ return 400 status
• If the pathname contains duplicated slashes (//) return 404 status

Examples

/file/index.html	returns public/index.html
