##Source Code layout ###Folder Layout

• src : Source code for the webserver
• Server : Runs the server and accepts connections
• Connection : Handles connection-related events (reading and writing)
• ConfigHandler : Encapsulates config parsing and access to config options
• ConfigParser : Parses the config
• Request and Response : Classes that represent parsed requests and responses
• RequestHandler : Parent to the webserver handlers that defines shared functionality
• EchoHandler : Echo handling
• StaticFileHandler : Static file handling
• ProxyHandler: Handle requests to a remote host by proxy
• test : Contains tests for each class
• build : build files

###Connection Class

• Bulk of interaction with other classes occurs here
• Connection::handle_read calls Request::parse to parse a request
• Connection::handle_read will call the error handlers if the request cannot be parsed or if the requested file is not found
• Connection::ProcessRequest will call the correct handler, if the request is valid and attempts to access a file that is present

###RequestHandlers

• EchoHandler : Echo client request.
• StaticFileHandler : Return static file to client.
• StatusHandler : Show the webserver status including details of request received and service provide.
• ErrorHandler : Handle different HTTP errors and show details.
• ProxyHandler : Open a new connection to a remote host and handle requests using new connection.
