This aim of the project was to understand how a Http Server work. The aim of the project is to help an individual understand of how a Http Server work. It was driven by 23 acceptance tests which expected to have features like:

• Post/Put/Get/Option/Head/Delete integration
• Public file listings/links
• Basic Auth
• File provider
• Partial file provider

Here is the basic flow of the Http server:

You can run the server this way:

Run the server

  gradle jar
  java -jar build/libs/server.jar -p 5000 -d /your/public/directory

You can connect to the server with netcat this way:

  nc localhost 5000

Test

Run unit tests

  gradle test

Run acceptence tests

  gradle jar
  cd cob_spec
  mvn package
  java -jar fitnesse.jar -p 9090

You can then going on the fitnesse test page which by default is: default test page

What's next?
