If Keep-Alive is enabled then this object will be reused for subsequent requests until the client breaks keep-alive. This usually happens when it times out. Because this could easily lead to a DoS attack, we keep track of the number of open processors and only allow 100 to be persistent active at any one time. Additionally, we do not allow more than 500 outstanding requests.
getFileExtension ( string filename ) : string	extracts the file extension from a filename
parseRequest ( ) : bool	parses the Request and determines if it's actually a valid one or not
process ( ) : void	This is the main method of each thread of HTTP processing. We pass this method to the thread constructor when starting a new connection.
readHeaders ( ) : bool	Reads the headers of the request and determines if they are valid or not

writeFailure ( ) : void
writeForbidden ( ) : void

writeResult ( int status, string message, long length, string mimetype ) : void
writeSuccess ( long length ) : void
writeSuccess ( long length, string mimetype ) : void
writeURL ( ) : void	We need to make sure that the url that we are trying to treat as a file lies below the document root of the http server so that people can't grab random files off your computer while this is running.

HttpProcessor() public method

Each HTTP processor object handles one client. If Keep-Alive is enabled then this object will be reused for subsequent requests until the client breaks keep-alive. This usually happens when it times out. Because this could easily lead to a DoS attack, we keep track of the number of open processors and only allow 100 to be persistent active at any one time. Additionally, we do not allow more than 500 outstanding requests.
