# TCP File Downloader
A program that downloads a file from the Internet given a URL over TCP. Watch a gif of me interacting with it below!
## 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:
1. Download the code as a ZIP:
3. Unzip the code:
4. Open the folder in an IDE, such as VSCode:
5. Obtain the URL of a file from the internet, copy it. Then, run the code by doing
```javac *.java
java ClientDriver -u
```
6. Interact with the file as you please!
