## Features

- Supports both `HTTP` and `HTTPS` URLs; if the protocol is `HTTP`, a regular `Socket` is used to establish a TCP connection; if the protocol is `HTTPS`,

  a secure connection is established with the server using an `SSLSocket`. 

- Operates in non-persistent HTTP mode; once the object is downloaded, the client closes the underlying TCP connection.

- URLs must be properly formatted with the following syntax: `protocol://hostname[:port]/pathname`, where `protocol` is either HTTP or HTTPS,

  `hostname` is the name of the web server, `[:port]` is an optional part which specifies the server port (default is 80 for HTTP and 443 for HTTPS),

  `pathname` is the path of the requested object on the specified host.

- Reads the server response line by line to first identify the end of the header fields (by looking for `\r\n`), and then reads the

  remainder of the server's response (the file itself) chunk-by-chunk using a buffer for improved performance. 

## If you want to start up the project on your local machine:
